Question

I tried to work this out, help

Answer 1

Two angles are complementary if the give 90° when summed.

Since angle 1 is right, angles 2 and 3 form a right angle as well, and thus they are complementary.

Answer 2

∠2

Explanation:

Complementary angles are angles that add up to 90°

So ∠3 + ∠2 = 90°
