Q1A Fill in the blanks by choosing correct alternative given below.
if one of the angle of a linear pair is 100° then the other angle is
(100 80 70,45')

Answer 1

The other angle is 80°

Explanation :

A linear pair is pair of adjacent angles formed by intersection of two lines such that ∠A + ∠B = 180°

100° + ∠B = 180°    ( Linear pair)

∠B = 180 - 100°

∠B = 80°
