A)
x = 40

D)
x = 45
Answers
Answer 1
Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
So your answer is 45
Answer 2
x is 45
the angle right above 135 is the same as x, and the angle above 135 is 45
