Question

The angle are supplementary and the larger is 20 degrees less than three times the smaller. Find the angle

Answer 1

Answer:

Angles are 50 and 130

Step-by-step explanation:

Let the smaller be x

Larger angle = 3x - 20

3x - 20 + x = 180....Supplementary angles

4x -- 20 = 180

4x = 180 + 20

4x = 200

x = 50

Smaller angle = x = 50

Larger angle = 3x - 20 = 130
