Question

If two interior angles on the same side of a transversal line intersecting two parallel lines are in the ratio 2 : 7,then find the measure of smaller angle.​

Answer 1

Answer:

40°

Step-by-step explanation:

sum of angles in same side of transversal in parallel line in 180°

Angles are in ration 2:7

let an angle be 2x and 7x

2x + 7x = 180

9x = 180°

x = 180/9 / 20°

here x = 20°

2x = 2×20 = 40°
