Question

answer question of the following

Answer 1

Let the supplement be 'x'
The angle is 1/5x or x/5

We know that -->
x/5 + x = 180
(x + 5x)/5 = 180
6x = 180 x 5
x = 150°

The angle is x/5 = 150/5 = 30°

Hence the required angle is 30°

Hope This Helps You!

Answer 2

The supplement= 180-x
x=1/5(180-x)
x=36-1/5x
-36=-1/5x-x
-36=-6x/5
36×5=6x
x=30°
