What is the reflection of point P(−1, 6) across the line y = x?

Answer:

<CDH = 110°

Step-by-step explanation:

Given <1 = 70°

Because BF ║ CD so <1 = <3 = 70° (corresponding angles are equal)

<CDH = 180° - <3

<CDH = 180° - 70°

<CDH = 110°

Answer:

125

Step-by-step explanation:

We are given that <1=70. Using that, we know that <5 also equals 70 because of the definition of vertical angles, we then can find <2 also by subtracting 70 from 180 and dividing it by 2 to get 55. <4=<2 and <6=<5, so using substitution we can get m<CDH=125

Answer:

123

Step-by-step explanation:

In a parallelogram, both pairs of opposite angles are congruent. Also, both pairs of opposite sides are parallel, meaning there are consecutive interior angles. Consecutive interior angles equal 180, so simply subtract 57 from 180 to find your missing angles.

Answer:

1. 30

2. 150

3. obtuse

4. acute

5. Adjacent

Step-by-step explanation:

The correct expression for the angles are;

1) m SUT equals  30 Degrees.

2) m TUW equals  150 degrees

3) TUW is obtuse angle

4) SUT is acute angle

5) TUW and SUT are Adjacent angles

Similar to corners, right angles have a 90° measure. Acute angles are less than ninety degrees. More than 90° but less than 180° are obtuse angles. Additionally, a straight angle is 180°, which is the point at which two lines merge into one by going in the same direction.

Any angle is composed of two rays that converge at a point known as the vertex. When two angles share a ray, it indicates that they are adjacent to one another.

Answer:

6 weeks.

Step-by-step explanation:

Let x be the number of weeks to be found.

Then  4.5x + 18 / 4x = 15/8

Cross multiply:

36x + 144 = 60x

24x = 144

x =  6  (answer).

In approximately 1.67 weeks (or rounded to 2 weeks), Theo and James will have savings in the ratio 15:8.

We can set up an equation to represent the savings of Theo and James over time. Let x be the number of weeks they have saved. Theo will have saved £4.50x and James will have saved £4x. We can set up the equation:

£4.50x / £4x = 15 / 8

Cross-multiplying the equation gives us:

8 * £4.50x = 15 * £4x

Simplifying the equation gives us:

36x = 60x

Dividing both sides by 36x gives us:

1 = 5 / 3x

Cross-multiplying again gives us:

3x = 5

Dividing both sides by 3 gives us:

x = 5 / 3

Therefore, in approximately 1.67 weeks (or rounded to 2 weeks), Theo and James will have savings in the ratio 15:8.

Answer:

The hose is ~70.71 ft long.

Step-by-step explanation:

We need to use Pythagorean theorem to figure this out. ( A^2 + B^2 = C^2)

So we first need to square 50 two times, since that's the length and height of the garden. This equals 5000.

Then we just need to find the root of 5000! This rounds out to about 70.71 ft.

Hope I could help! :)

The length of the hose which is ​stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft

The diagonal of the square is the distance from opposite vertices of it. There are two diagonals in a square which are equal in measure.

To find the diagonal of the square, the following formula is used.

d=a√2

Here, (a) is the length of the side of the square.

The side of a square garden is 50 ft long. One hose is stretch from one corner of the garden to another corner across the diagonal of it. Thus, the length of the diagonal is,

d=a√2

d=(50)√2

d=70.72 ft

Answer:

The perimeter of the equilateral triangle, P = 24 units

Step-by-step explanation:

All sides of an equilateral triangle are equal. The height of the equilateral triangle is given by :

[tex]h=\dfrac{\sqrt{3} }{2}\times a[/tex]

a is the side of triangle

If the height of an equilateral triangle is, [tex]h=4\sqrt{3}[/tex]

Equation (1) becomes,

[tex]a=\dfrac{2h}{\sqrt{3} }[/tex]

Put h in above formula. So,

[tex]a=\dfrac{2\times 4\sqrt{3}}{\sqrt{3} }[/tex]

a = 8

So, the side of triangle is 8. The sum of all sides is called perimeter of any figure. So,

[tex]P=8\times 3[/tex]

P = 24 units

So, the perimeter of the equilateral triangle is 24 units. Hence, this is the required solution.

Final answer:

To find the perimeter of the equilateral triangle with a height of 4√3, we determine the side length using the relationship between the height and side length of the triangle, and then multiply by three to get a perimeter of 24 units.

Explanation:

The height of an equilateral triangle is given as 4√3. To find the perimeter, we need to determine the length of a side of the triangle. In an equilateral triangle, the height (h) creates a right-angled triangle where the height is opposite to a 60° angle, and the half of a side of the triangle (half-base) is adjacent to it. The relationship is given by the equation h = (a√3)/2, where a is the side length of the equilateral triangle. By substituting the height with 4√3, we get:

4√3 = (a√3)/2 → a = 8

Since all sides of an equilateral triangle are equal, the perimeter is three times the side length, which means the perimeter P = 3 × 8 = 24 units.

Answer:b

Step-by-step explanation:

You're answer is b. All you have to do is a measurement

Answer:

B) 1/2 (154° - 46°)

Step-by-step explanation:

Here ∠XYZ is an angle subtended by two chords from a point outside of the circle.

It is a one of the circle.

If the angle subtended by two chords from the outside point of the circle, the measure of the angle is 1/2 times difference of the major arc and minor arc.

Here Major arc = 154° and minor arc = 46°

Applying the rule, we get

m∠XYZ = [tex]\frac{1}{2} (Major arc - Minor arc)[/tex]

m∠XYZ = 1/2 (154° - 46°)

Answer:

65 ft by 39 ft

Step-by-step explanation:

Let x ft be the length of each part and y ft be the width of each part. The total perimeter of all 5 parts is

[tex]6x+10y=780[/tex]

The length of the large rectangle is 5y ft and the width of the large rectangle is x, so the total area is

[tex]A=x\cdot 5y[/tex]

From the first equation,

[tex]y=78-0.6x[/tex]

Substitute it into the area expression:

[tex]A(x)=x\cdot 5(78-0.6x)=390x-3x^2[/tex]

Find the derivative:

[tex]A'(x)=390-3\cdot 2x=390-6x[/tex]

Equate it to 0:

[tex]390-6x=0\\ \\6x=390\\ \\x=65[/tex]

Then

[tex]y=78-0.6\cdot 65=78-39=39[/tex]
