Question

. The two supplementary angles are in the ratio 1:8. find the angles.
​

Answer 1

Answer:

Let 1x and 8x be the angles

Sum of supplementary angles =180

A. T. Q.

1x+8x =180

9x =180

x =180/9

x =20

Angles are 1*20=20

and second is 8*20=160

Answer 2

Step-by-step explanation:

Let the common multiple be x .

1x+8x=180 ( The angles are supplementary )

9x=180

x=180/9

x=20

The angles are ,

x= 20⁰

8x=8×20=160⁰
