Question

A is a supplement of B , A is a complement of C , and mB= 124°. Find mB+mZC. mB +mC=mB+mC= °

Answer 1

If m∠B is 124°, then its supplement is 56° (180°- 124° = 56°). So, m∠B is 56°

Since ∠C is a complement of A, then C = 90° - 56° = 34°.

Therefore, m∠B + m∠C = 124° + 34° = 158°.

The answer is 158°.
