Answer:
55
Step-by-step explanation:
The angles are complementary as they add up to make a right angle/ 90° as indicated by the small square. So let's make an equation and solve for x :
x-20 + x = 90
Add 20 to both sides :
x+x = 110
2x = 110
Divide both sides by 2 :
x = 55
Hope this helped and have a good day
