Question in the picture!!!!!!!!
torisob [31]

Answer:

∠A and ∠C are vertical and equal in measure

∠C is adjacent to the angle that is 27°

∠C and ∠B are supplementary

∠A and ∠B are supplementary AND adjacent

All of them are correct

Step-by-step explanation:

<u><em>This is just how to find the angles.</em></u>

"When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex." - MathPlanet

The 27° and the 90° angles added up equal ∠B

∠B = 117°

360°-117°-117°=∠A & ∠C

∠A + ∠C = 126°

∠A=∠C=63°

A square has an area of 576 square inches. How long is each side in feet?
Maru [420]
The area of this square is said to be 576 square inches.
The formula for the area of a square is the length of one side squared.
Let's use l to represent the side length.
This means l^2 = 576.
To find l, find the square root of both sides.
<span>√576 = 24
</span>
The length of each side of the square is 24 inches.
But the question is asking for it in feet.
12 inches = 1 foot so 24 inches = 2 feet
This means each side of the square is 2 feet long.

Answer:
2 feet
