Question

14 The angles that form a linear pair are in the ratio 2:7

Find the measure of each angle.​

Answer 1

Answer:

smaller angle is 40° and larger is 140°

Explanation:

let the common ratio be x

therefore, the angles are 2x and 7x

since they are a pair of linear pair hence their sum would be 180°

2x + 7x = 180°

9x = 180

x = 20°

therefore, the angles so formed are :

2x = 40°

7x = 140°

Answer 2

Answer:

sum of linear pairs =180°

let common ratio be x

2x+7x =180

9x=180

x=180/9

x=20

2x =2*20=40

7x =7*20=140

so 40and 140 are your answers
