Question

An angle is one-fifth of its supplement find the measure of the angle​

Answer 1

Let one angle = x°

It’s supplementary angle = ( 180 – x )°

According to the problem given ,

x = (180 – x ) / 5

5x = 180 – x

5x + x = 180

6x = 180

x = 180/6

x = 30°

Therefore ,

First angle = x = 30°

It’s supplement = 180 – x

= 180 – 30

= 150°
