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
