Question

Find the measure of the supplementary angle of ${132}^o$

• A. ${48}^o$
• B. ${32}^o$
• C. ${42}^o$
• D. ${38}^o$

Answer 1

The correct option is A ${48}^o$

Two angles are Supplementary when their sum is equal to ${180}^{\circ }$.

If one angle $={132}^{\circ }$, let the other angle be $x$.

Hence, $x+{132}^{\circ }={180}^{\circ }$

$x={180}^o-{132}^o={48}^o$

Hence, supplementary angle is ${48}^o$.
