Question

155°,Measure of one angle of linear pair is given. Find the measure of another angle.

Answer 1

measure of one angle is 155° and let the other angle be x and now

x + 155 = 180° ( Linear Pair)

x = 180 - 155

x = 25°

Answer 2

Solution :

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

A pair of adjacent angles are said

to be a linear pair of angles if their

sum is 180°.

**********************************†*********

Here ,

One angle ( x ) = 155°

Let Second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 155°

=> y = 25°

Therefore ,

Required measure of another angle

is 25°
