Question

if 2 suplementary angles are in the ratio 2:7 then the angles are​

Answer 1

Answer:

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

∘

hope it helps u :)

Answer 2

Ratio of two supplementary angles = 2:7

Let the common multiple be x

1st angle = 2x

2nd angle = 7x

According to The problem

1st angle + 2nd angle = 180⁰

2x + 7x = 180⁰

9x = 180⁰

=> x = 180/9 = 20

Therefore,

1st angle = 2x = 2×20 = 40⁰

2nd angle = 7x = 7×20 = 140⁰
