Question

Measure of one angle of linear pair is 108°,then find the measure of another angle.

Answer 1

For Linear pair

The Sum of two angles = 180°

so X + Y = 180°

Given Angle = X = 108°

so

108° + Y = 180°

Y = 180° - 108°

Y = 72°

So. other angle of the Linear pair is 72°

Answer 2

Solution :

***************************************
A pair of adjacent angles are said

to be a linear pair of angles of their

sum is 180°.

*****************************************

Here ,

one angle ( x ) = 108°

Let the second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 108°

=> y = 72°

Therefore ,

second angle = y = 72°
