Question

Two angles are supplementary. The angle is 20 degree more than thrice the smaller. Find the angles

Answer 1

Answer:

Given angle = x

Second angle = 20 + 3x

x + (20 + 3x) = 180

4x + 20 = 180

4x = 160

x = 40

So, given angle = 40 degrees.

Second angle = 140 degrees

Answer 2

Answer:

20+3x+x=180°

20+4x=180°

160=4x

x=40°

x=140°

one angle 40 another is 140
