An angle is 1/5 th of its supplementary. The measure of the angle is​

Answer 1

Answer:

150

Step-by-step explanation:

Hi ,

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°

I hope this helps you.
