Question

an angle is one fifth of its supplement .the measures of angle is 15° ,30° ,45° ,150°​

Answer 1

Answer:

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°

Answer 2

Answer:

we know supplementary angle is 180 degree

180/5 = 36 degree

180/4 = 45 degree
