Question

Two angles are supplementary. The first angle is 3X degrees. The second angle is 2X +25 degrees determine the measure of the smaller angle.

Answer 1

The smaller angle is 2x+5=87

Explanation:

Since the angles are supplementary,

3x+2x+25=180°

=>5x+25=180°

=>5x=155

=>x=31

So substituting x in both angles, 3x=93° and 2x+25=87°, therefore our answer
