Which angle is complementary to

Hello! Remember you need to write complete questions in order to find good and exact answers. Here your question is incomplete so I could help you in a general way. Recall that two angles are complementary if and only if they add up to 90°. So, if we have to angles, namely:

∠A and ∠B

And angle ∠A = 35°, then this is complementary to ∠B as the following form:

∠A + ∠B = 90°

∴ 35° + ∠B = 90°

∴ ∠B = 90° - 35°

∴ ∠B = 55°

Finally, ∠A and ∠B are complementary because they add up to 90°

it is b)
