Question

Two angles are supplementary. The measure of the larger angle is 12 less than 3 times the measure of the smaller angle.Find the measure of each angle

Answer 1

Answer: The measure of the smaller angle is 48,and the larger angle is 132.

Explanation:

Answer 2

48 , 132

Explanation:

Let smaller angle = x

Larger angle = 3x - 12

x & (3x - 12) are supplementary

So, x + 3x - 12 = 180°

4x - 12 = 180

4x = 180 +12

4x = 192

x = 192/4

x = 48°

Larger angle = 3*48 - 12 = 144 - 12 = 132
