Answer:
Step-by-step explanation:
You have to make the following assumptions
- the figure is a square
- the right angle is in the light blue large square's lower left corner
All triangles have 3 angles
All triangles have 3 angles adding to 180
Formula
x + x + 90 = 180 Subtract 90 from both sides, Combine the xs
2x +90-90 = 180-90 Combine
2x = 90 Divide by 2
2x/2 = 90/2
x = 45
The answer is in the middle yellow rectangle
