Question

Two angles are supplementary and the larger is 20° less than three times the smaller. Find the angles.

please send the full process of the question.​

Answer 1

Step-by-step explanation:

Let smaller angle be x degree

=> larger angle= 3x - 20

Since these angles are supplementary

=> x + 3x - 20 = 180

=> 4x = 200

=> x = 50

=> 3x - 20 = 150 - 20 = 130

ie, smaller angle = 50 deg

& larger angle = 130 deg
