Question

Two Co interior angles are in the ratio 2:7 . If two parallel are intersected by a transversal then the smaller angle id

Answer 1

Step-by-step explanation:

2x+7x=9x

9x=180

x=20

the angles are 40 and 140

Answer 2

Step by step explanation:

let two angles are 2x,7x

2x+7x= 180 (because sum of two co interior angles are 180

9x = 180

x =180/9

x =20

Therefore two angles are 2(20)=40

7(20)=140
