Answer:
x = 8, and y = 21
Explanation:
You probably don't need this since this question was yesterday, but if you still need help:
I'm not the best at explaining but, Angles EOF and FOG are complementary, making 3y equal to 63. 63 divided by 3 is 21 making y = to 21. Angles AOE and GOB are also complementary adding them in the equation makes 9x + 18.
90 degrees minus 18 is 72, 72 divided by 9 is 8. Making 8 equal to x. 9x +18 ((9)8 + 18) is equal to 90 degrees.
Try to make something better again I'm not good at explaining.
