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
