Question

two angles of a linear pair are in the ratio of 2:7 find the angle​

Answer 1

Answer:

A/q,

2x + 7x = 180°(as linear pair equals 180°)

9x = 180°

x = 180/9

x = 20°

therefore, the angles are..2x = 20*2 = 40°

and 7x = 20*7 = 140°

Answer 2

Answer:

x=20

Step-by-step explanation:

2x+7x=180

9x=180

x=180÷9

x=20

2x=20×2

=40

7x=20×7

=140
