Quadrilateral ABCD is inscribed in this circle.
What is the measure of ∠A ?
Enter your answer in the box.
Answers
The measure of ∠A is 137°.
Solution:
Given data:
Angle A = 43°
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠A and ∠C are opposite angles in a cyclic quadrilateral.
In cyclic quadrilateral, opposite angles are supplementary.
⇒ m∠A + m∠C = 180°
⇒ 43° + m∠A = 180°
Subtract 43° from both sides of the equation, we get
⇒ m∠A = 137°
Hence the measure of ∠A is 137°.

Step-by-step explanation:
First you take each width and multiply it by 2 to get both widths.
Then you take 120 and subtract each width from it because it's 120 feet for the entire fence.
Next you end up with the length.
Finally you multiply the length by the width to get the area.

Vertical and horizontal line (1,-4)—do X=blank and Y=blank
Answers
Answer:
x = 1 and y = - 4
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through.
Here the line passes through (1, - 4) with x- coordinate 1, thus
x = 1 ← equation of vertical line
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line goes through.
Here the line passes through (1, - 4) with y- coordinate - 4, thus
y = - 4 ← equation of horizontal line

Answers
Final answer:
The value of the expression (132-122)÷5 is 2 after performing the subtraction followed by division.
Explanation:
Evaluating the expression (132−122)÷5 involves two operations: subtraction and division.
First, we subtract 122 from 132, which gives us 10.
Then, we divide the result by 5.
The division of 10 by 5 yields 2.
Therefore, the value of the expression (132−122)÷5 is 2.

Grace starts with 100 milligrams of a radioactive substance. The amount of the
substance decreases by each week for a number of weeks, w. She writes the
expression 100(-)w to find the amount of radioactive substance remaining after w
weeks.
Ryan starts with 1 milligram of a radioactive substance. The amount of the substance
decreases by 40% each week for a number of weeks, w. He writes the expression (1 -
0.4)" to find the amount of radioactive substance remaining after w weeks.
Use the drop-down menus to explain what each part of Grace's and Ryan's
expressions mean.
Answers
Answer:
100 is grace's initial amount. w is how much of the substance is being decrased each week. in ryan's equation, 1 is 100% of the substance, so the initial amount, and 0.4 is the amount that is being decreased.
Step-by-step explanation:
Answer:
100= Initial Amount
1/4= decay factor for each week
w= number of weeks
1/4w= decay factor after w weeks
1 - 0.4= decay factor for each week
w= number of weeks
0.4= percent decrease

The distance from home to school will be 5 meters.
What is the Pythagorean theorem?
Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
From the given image the distance between the home and school is followed by the square 3 meters from the home and the school is 4 meters making a right-angle triangle.
The minimum distance between the school and the home will be calculated as;-
D = √ ( 3² + 4² )
D = √ ( 25 )
D = 5 meters'
Therefore, the distance will be 5 meters.

Which inequality is equivalent to -m> 15
Answers
This inequality can be simplified.
~Divide -1 to both sides (flip the symbol since we're dividing a negative number)
-m/-1 < 15/-1
m < -15
Best of Luck!
Answer:
m < -15
Step-by-step explanation:
Step 1: Multiply both sides by -1
-m > 15
-m * -1 > 15 * -1
Since you multiply by a negative, you must flip the sign
-m * -1 > 15 * -1
m < -15
Answer: m < -15
The farthest distance a satellite signal can directly reach
is the length of the segment tangent to the curve of Earth's
surface. If the measure of the angle formed by the tangent
satellite signals is 135, what is the measure of the intercepted
satellite
arc on Earth? (The figure is not drawn to scale.)
Answers
Answer:
45°
Step-by-step explanation:
The sum of interior angles of the quadrilateral that has vertices at the center of the Earth, the two points of tangency, and the satellite is 360°. The angles at the points of tangency are 90°, so the angle at the satellite and the central angle are supplementary.
The arc has a measure of 180° -135° = 45°.
Gavin is training for a marathon and varies his workouts from day to day. Gavin ran 10 MPH during Monday's workout and 50% slower during Tuesday's workout. How fast did he run on Tuesday?
MPH
Answers
Solution:
Given that,
Gavin ran 10 MPH during Monday's workout
50% slower during Tuesday's workout
Therefore,
Speed in tuesday = 50 % slower than monday
Which means,
Speed in tuesday = 10 - 50 % of 10
Solve the above
[tex]\text{ Speed in tuesday } = 10 - \frac{50}{100} \times 10\\\\\text{ Speed in tuesday } = 10 - 0.5 \times 10\\\\\text{ Speed in tuesday } = 10 - 5\\\\\text{ Speed in tuesday } = 5\\\\[/tex]
