Question

Need help ASAP I’m trying to understand

Answer 1

100 degrees

Explanation:

The opposite angle will always be the same. since the opposite is 5a, then x = 5a. x is 5a, and 9a is 180 degrees so x=180(5/9), which is equal to 100 degrees.

Answer 2

Explanation:

5a+4a=180

a=20

5a=X

X=5×20

=100°
