Answer:
Angle 1= 45°
Angle 2= 90°
Explanation:
Angle is found when you divide 90 by 2
We do this because all edges of a square add up to 90 and this angle is split in half, which is why we divided by 2
The to find angle 2 you get 45 for the left side of the triangle, 45 on the right side add them, which will give you 90, then subtract from 180 because angles in triangle equals 180 when you do this you get 90.
