Answer:
y = 45
x = 45
Step-by-step explanation:
The line that seperates the square or the 90 degree angle is called an angle bisector which seperates angles equally. So when you seperate 90 degrees equally it becomes 45 degrees on each side.
Making y = 45 degrees.
All triangles equal 180 degrees. For the triangle on the right we already have two of the angles. "y" which is 45 degrees and the square which is 90 degrees. Add those up and you get 135 degrees. Subtract by 180 and you get 45 degrees.
Making x = 45 degrees.
