Question

Two angles are supplementary angles. If measure of one angle is ${66}^{\circ }$, then find the measure of another angle.

Answer 1

Two angles are supplementary angles

$\therefore \angle A+\angle B={180}^{\circ }$

$\therefore {180}^{\circ }-{66}^{\circ }={114}^{\circ }$

Thus, the supplementary angle of given angle is ${114}^{\circ }$
