Question

if two supplementary angles are in in 2:7 find the angles. solve this question don't write the answer directly solve it​

Answer 1

Answer:

let the angles be 2x and 7 x respectively

2x+7x=9x

9x is a supplementary angle which is equal to 180

9x=180

x=180/9=20°

therefore the angles are 40° and 140°

Answer 2

Hii

you are welcome in my ans

let the ratio be x

sum of two supplementary angle =180

so According to question

2x + 7x =180

9x = 180°

x=20°

so

angle 1 = 7*20 =140°

angle 2 = 2*20°= 40°
