Question

Two supplementary angles are in the ratio 2:7.Find the the measure of angles​

Answer 1

Let the angles be 2x and 7x

Angles are given supplementary

2x+7x=180 ∘

9x=180 ∘

x=20 ∘

So the angles are 2×20 ∘ =40 ∘

and 7×20∘=140∘

Step-by-step explanation:

Answer 2

Answer:

let the angles be 2x and 7x

the sum of angles will be180

2x+7x=180

9x=180

x=180÷9

x=20°

the angles will be

2x=2×20=40°

7x=7×20=140°
