Question

Angle A and Angle B are complimentary angles. If the measure of Angle A is 42 find the measure of angle B

Answer 1

Here's my step-by-step explanation:

@Jdoe0001 already gave you a hint in the comment section, and that's a real giveaway, but I'll expand on the hint.

Complimentary angles add up to 90°, and A and B are complimentary, then A+B = 90°. A proof.

Substitute. 42° + B = 90°.

B = 90° - 42°

B = 48°

Hope this helps!

Answer 2

Step-by-step explanation:

Given :

A + B = 90⁰

42⁰ + B = 90⁰

B = 48⁰
