Answer:
(-3,5)
Step-by-step explanation:
When you reflect over the x axis, the y value's sign changes.
So we have:
-3,5
Given:


To find:
The value of x and measure of ∠A.
Solution:
Let C be angle the vertically opposite to ∠A.
The reference image for answer is attached below.
By vertical angle theorem:
m∠A = m∠C
m∠C = 10x + 24°
By the corresponding angle theorem:
m∠C = m∠B

Subtract 24° on both sides.

Subtract 6x from both sides.

Divide by 4 on both sides.

The value of x is 12°.



The measure of ∠A is 144°.
Answer:
About 1,237 cubic feet.
Step-by-step explanation:
The first step is to know the formula for the volume of a cylinder.
V = pi * r^2*h
You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:
V = pi * 7.5^2 * 7
Answer
75 inches
