Page no 101

1. Ans,

Therefore angle 3 and angle1 are vertically opposites angles,

angle 3 = angle 1

But, angle1 = 30 degree

angle 3 = 30 degree

Again, angle 3 and angle 2 form a linear pair.

So, angle 3 + angle 2 = 180 degree

30 degree + angle 2 = 180 dedree

angle 2 = 180 degree - 30 degree

= 150 degree

angle 2 = 150 degree
