Question

If L is parallel to M and t is transversal. find x

Answer 1

Solution :

Given l // m, t is a transversal .

1x + 3x = 180°

[ Since , Sum of interior angles same

side of the transversal are

supplementary ]

4x = 180

=> x = 180/4

=> x = 45

••••

Answer 2

L is parallel to M and t is transversal.
We know that Angles on the same side of transversal are supplementary.
=>3x + 1x = 180°
=>4x = 180°
=>x = 45°.
