Question

145° - Write the measure of supplementary angle of the given angle.

Answer 1

For supplementary Angle

The Sum of two angles = 180°

so X + Y = 180°

Given Angle = X = 145°

so

145° + Y = 180°

Y = 180° - 145°

Y = 35°

So. supplementary angle of the given angle is 35°

Answer 2

Solution :

******************************************
Two angles are said to be

supplementary if their sum is 180°

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

Here ,

one angle ( x ) = 145°

second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 145°

=> y = 35°

Therefore

Supplementary angle of 145° = y = 35°
