Answer:
x = 15.3°
Step-by-step explanation:
Trig identities:

where
- x = angle
- O = side opposite the angle
- A = side adjacent the angle
- H = hypotenuse

Answer:
so that's how you plot their intersection
The measures of x and y are 291.
First find the area of the rectangle: 10 * 40 = 400
Now, since the square has the same area, we'll find the side lengths of the square by just finding the square root of 400 which is 20. You can do this with a calculator. So the side length of any side on the square is 20.
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
