Question

In the fig line L ||to m and line n is the transversal with respect to give inforation find the value of a.. give fast answer..plz​

Answer 1

2a+120 = 180(because sum of

co interior angles is 180)

2a =180-120

2a=60

a=60/2

a=30

hope it will help you

Answer 2

Given that

L is parallel to M

Now,

Since, L and M are parallel to one another

So,

120+2a=180° (being sum of co-interior angle)

or, 2a=180°-120°

or,2a= 60°

or, a=60°/2

So, a = 30°
