Question

What is the supplementary angle of 78°?

Answer 1

Supplementary angles are 2 angles that have the sum of 180°.

Since you have 78° you will take that away from 180°

180°-78° = 102°

This equals 102°. Therefore, the supplementary angle of 78° is 102°

Answer 2

The supplementary angle of 78° is 102°

Explanation:

supplementary angle, sum = 180°

180 - 78 = 102°

The supplementary angle of 78° is 102°
