Question

two supplementary angles are in ratio 2:7 . the measure of those two 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

∘

Answer 2

Answer:

hi,

the answer is 40 & 140

here's how

Step-by-step explanation:

angle a + angle b = 180°

2x + 7x = 180° (let the ratio be x)

9x = 180°

x = 180 ÷ 9

x =20°

∴ 2x = 2 x 20 = 40°

   7x = 7 x 20 = 140°
