Answer:

x = 30

Explanation:

sum of all the angles in a quadrilateral (4-sided shape) add up to 360°

the two bottom angles are 90°

so the two top angles must add up to (360 - 90 - 90)° = 180°

this means that (2x + 25) + (3x + 5) = 180

2x + 3x + 25 + 5 = 180

5x + 30 = 180

5x = 180 - 30 = 150

x = 150/5 = 30
