Question

50°,Measure of one angle of linear pair is given. Find the measure of another angle.

Answer 1

For Linear pair

The Sum of two angles = 180°

so X + Y = 180°

Given Angle = X = 50°

so

50° + Y = 180°

Y = 180° - 50°

Y = 130°

So. other angle of the Linear pair is 130°

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 ) = 50°

Let second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 50°

=> y = 130°

Therefore ,

Required measure of another angle

is 130°
