Question

an angle is 1/5 of its supplement than the measure of other angle​

Answer 1

let angle be X

X=(180-X)/5

5X=180-X

6X=180

X=30

SO ANGLE IS 30°

Answer 2

Heyaa...

_______________________________

Let there be two angles X & y.

Given:- X + y = 180° ------(1)

X = y/5 ---------(2)

Solution:- Putting the value of eq. 2 in 1. We get,

y/5 + y = 180

6y = 900

y = 150°

And, X = 30°

Hope it helps❤️
