Question

$\angle A$ is supplementary to $\angle B,\angle B$ is complementary to $\angle C$. If $\angle A={118}^{\circ }$, what is the measure of $\angle C$ ?

• A. ${62}^{\circ }$
• B. ${34}^{\circ }$
• C. ${118}^{\circ }$
• D. ${28}^{\circ }$

Answer 1

The correct option is D ${28}^{\circ }$

$\angle B={180}^{\circ }-\angle A={180}^{\circ }-{118}^{\circ }={62}^{\circ }$

$\angle C={90}^{\circ }-{62}^{\circ }={28}^{\circ }$.
