Question

the two supplementary angles are in 2:5, then the angles are______​

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

∘

Answer 2

Answer:

supplementary angle =180..

2x+5x=180

7x=180..

x=180/7=25.71..

2*25.71=51,.42

5*25.71=128.58
