Question

Find the supplementary angle corresponding to the following angle.

$\theta ={140}^{\circ }$

Answer 1

Supplementary angles:- if the sum of two angles is ${180}^{\circ }$ then the angles are said to be supplementary to each other

Given $\theta ={140}^{\circ }$

$\therefore$ the supplementary angle is ${180}^{\circ }-{140}^{\circ }={40}^{\circ }$

The correct answer is ${40}^{\circ }$
