Question

In the given figure 2 parallel lines PQ and RS are intersected by a transversal l such that angle 1: angle 2= 7:2. Find angle 1 and angle 2​

Answer 1

Answer:

Angle 1 = 20° , Angle 2 = 40°

Step-by-step explanation:

let the angle 1 and angle 2 be x

x + 7 + 2 = 180° ( sum of all angles = 180° )

9x = 180°

x = 180° / 9

x = 20°

Angle 1 = 20° × 1

= 20° Ans.

Angle 2 = 20° × 2

= 40° Ans.
