CAF and EFA are congruent because they are corresponding angles of parallel lines cut by a transversal. ∠GAC ≅ ∠HFD by the transitive Property of Congruence.

Angles that are of the same measurement are called congruent.

Suppose that two angles ∠A and ∠B are of the same measure,

then

[tex]m\angle A = m\angle B[/tex]

is the notation to say that they are of same measurement, where the small m shows that its the measurement of the angles they're preceding.

We write the congruency between them as;

Answer: classroom numbers are 353 and 355

Step-by-step explanation:

Let x represent the first no

Then x+2 represents the second number

Turn the question to an equation= x - (x +2) =708

Therefore, 2x + 2= 708

2x= 708-2

2x= 706

x= 353 and x+2= 355

Hope you understand, please mark brainliest.

Answer:

The first number is 353, and the second is 353 + 2, or 355.

Step-by-step explanation:

Represent the first number by n and the next by n + 2.  

Then n + (n + 2) = 2n + 2 = sum of the two numbers = 708.

Subtracting 2 from both sides yields 2n = 706.  Dividing both sides of this latest result by 2 yields n = 353.

The first number is 353, and the second is 353 + 2, or 355.

Step-by-step explanation:

Answer:

no

because it should be 99

In the given diagram, line AB is parallel to CB. i.e. AB∥CD ∠EGB = 57°

then the value of ∠EHD = 57°

In this diagram, since AB is parallel to CD, we can infer that ∠EGB and ∠EHD are corresponding angles, and corresponding angles are congruent when a pair of parallel lines are intersected by a transversal. Given that ∠EGB = 57°, we conclude that ∠EHD is also 57° based on the properties of corresponding angles. Thus, ∠EHD = 57°.

When two parallel lines are intersected by a transversal, the corresponding angles formed on either side of the transversal are congruent. In this case, we are given that line AB is parallel to line CD, which implies that ∠EGB and ∠EHD are corresponding angles.

Given: ∠EGB = 57° (Given in the diagram)

Since AB || CD, ∠EGB ≅ ∠EHD (corresponding angles are congruent).

Therefore, ∠EHD = ∠EGB = 57°.

Hence, ∠EHD is also 57° based on the properties of corresponding angles.

In mathematical terms, we use the property of corresponding angles formed by a transversal intersecting two parallel lines to establish the congruence between ∠EGB and ∠EHD. This property is a fundamental aspect of geometry dealing with angles and parallel lines.

because the hundred thousand place value is the digit 5 or higher, the millions rounds up!! in this case, the 3 in the millions rounds up to 4 and the rest of the digits on the right turn to 0, also remember commas!!!!!

3 887 860 rounded to the nearest million is 4 000 000.

From the given number 3 887 860, stating the place value of each digit

We have 0 ones (or unit), 6 tens, 8 hundreds, 7 thousands, 8 ten thousands, 8 hundred thousands and 3 million.

Hence, the number we are rounding is 3 (since we are asked to round to the nearest million)

To round a number, we either round up or round down.  

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down; and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Since, the number that follows the digit we are rounding is 8, then we round up. We round up by adding 1 to the digit we are rounding and turn the remaining numbers to zeros.

(3+1 = 4)

Hence, 3 887 860 rounded to the nearest million is 4 000 000.

Answer: Yes they are equal

Step-by-step explanation: First you have to solve 2(11x-6)-18:

2(11x-6)-18

22x - 12 - 18

22x - 30

They equal!

Answer:

0

THE RIGHT HAND SIDE IS EQUAL TO THE LEFT HAND SIDE.

Step-by-step explanation:

2(11x-6)-18 is equal to 22x-30

the above question can as well be expressed as

2(11x-6) - 18 = 22x -30

the next thing is to apply the BODMAS(BRACKET, OF, DIVISION, MULTIPLICATION, ADDITION , SUBTRACTION.) rule by first opening the bracket

22x - 12 -18 = 22x -30

We will proceed to collect the like terms

22x -22x = -30+12+18

0 = -30 +30

0=0

the answer is = 0

THEREFORE THE RIGHT HAND SIDE IS EQUAL TO THE LEFT HAND SIDE.

9 green marbles are expected in the representative sample.

The expected number of green marbles is 0.27 times the number of orange marbles in the representative sample.

Step-by-step explanation:

Given that,

The ratio of orange marbles to green marbles is in proportion to the ratio of orange marbles to green marbles in the representative sample.

To find the value of x :

The proportions are 77/21 = 33/x

Cross multiplying the denominators and keeping x alone on one side,

x = (33 × 21) ÷ 77

x = 693 ÷ 77

x = 9 green marbles.

Therefore, the number of green marbles expected in the representative sample is 9.

To find the how many times the green marbles is to the number of orange marbles in representative sample = 9/33 = 0.27 times.

The green marbles is 0.27 times to orange marbles in the representative sample.

angles formed by these tosses are  [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.

Step-by-step explanation:

Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.

The Law of Cosines (also called the Cosine Rule) says:

[tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

⇒ [tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]

⇒ [tex]c^2 -a^2 - b^2 = -2ab (cosx)[/tex]

⇒ [tex](cosx) =\frac{ c^2 -a^2 - b^2}{ -2ab}[/tex]

⇒ [tex](cosx) =\frac{(8.6^2 - 5.8^2 - 7.5^2)}{ ( -2(5.8)7.5)}[/tex]

⇒ [tex](cosx) =0.18310[/tex]

⇒ [tex]cos^{-1}(cosx) = cos^{-1}(0.18310)[/tex]

⇒ [tex]x = 79.45[/tex]

The Law of Sines (or Sine Rule) is very useful for solving triangles:

[tex]\frac{a}{sin A} = \frac{ b}{sin B} = \frac{c}{sin C}[/tex]

We can now find another angle using the sine rule:

⇒[tex]\frac{ 8.6 }{ sin 79.45} = \frac{7.5}{ sin Y}[/tex]

⇒[tex]sin Y = \frac{(7.5 (sin 79.45))}{ 8.6}[/tex]

⇒[tex]Y = 59.02 degrees[/tex]

So, the third angle =[tex]180 - 79.45 - 59.02 = 41.53 degrees.[/tex]

Therefore, angles formed by these tosses are  [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.

The question appeared to ask about the impact of dilation on a polygon's perimeter, but the scale factor was not provided. Generally, the perimeter of a dilated polygon is the original perimeter multiplied by the scale factor. Another part of the student's question involved calculating the actual diameter of a swimming pool from a scale drawing using a provided scale factor.

The student appears to have asked a question about a dilation of a polygon and its effect on the perimeter, as well as having other queries related to scale factors and how they apply to various geometric figures and real-life objects. Unfortunately, the specific scale factor for the dilation in question 5 is not provided. However, generally speaking, when a figure is dilated by a scale factor, the length of all sides is multiplied by that factor. Given that the perimeter is the sum of all side lengths, the perimeter of the dilated polygon would also be multiplied by the same scale factor. So if a polygon has a perimeter of 18 units and it is dilated by a scale factor, to find the perimeter of the dilated image we multiply the original perimeter by the scale factor. It's important to note that without knowing the exact scale factor, we cannot determine what the new perimeter would be.

For question 12, to find the actual diameter of the pool, we need to use the scale factor provided, which is 1/72. If the scale drawing shows a diameter of 1(1/2) inches, we can calculate the actual diameter using the following:

The rest of the calculations follow a similar method, using the respective scale factors and measurements to determine the actual sizes or scale sizes of objects.

The correct option is d. [tex]30\ units[/tex]. This means that the original polygon was dilated with a scale factor of to obtain the image with a perimeter of [tex]30\ units.[/tex]

To find the perimeter of the image of a polygon after dilation with a scale factor, we need to understand how dilation affects the dimensions.

1. Perimeter of the original polygon:

Let's denote the original perimeter of the polygon as [tex]\( P \)[/tex]. According to the problem, the original perimeter is [tex]18 \ units[/tex]

[tex]\( P = 18 \) \ units[/tex]

2. Dilation with a scale factor:

Dilation with a scale factor [tex]\( k \)[/tex] multiplies all dimensions (lengths of sides) of the polygon by [tex]\( k \).[/tex]

3. Perimeter after dilation:

After dilation with a scale factor [tex]\( k \)[/tex], the perimeter [tex]\( P' \)[/tex] of the polygon's image is given by:

[tex]\( P' = k \times P \)[/tex]

Here, [tex]\( k \)[/tex] is the scale factor.

4. Calculating the perimeter of the image:

The problem states that the polygon is dilated with a scale factor of [tex]\( \sqrt{3} \)[/tex]. So, [tex]\( k = \sqrt{3} \).[/tex]

Now, calculate [tex]\( P' \)[/tex]

[tex]\( P' = \sqrt{3} \times 18 \)[/tex]

[tex]\( P' = 18 \times \sqrt{3} \)[/tex]
