A) $297 ^ { \circ } , - 63 ^ { \circ }$
B) $477 ^ { \circ } , - 243 ^ { \circ }$
C) $417 ^ { \circ } , - 183 ^ { \circ }$
D) $234 ^ { \circ } , - 117 ^ { \circ }$
E) $297 ^ { \circ } , - 243 ^ { \circ }$

Question

Quizplus · Accepted Answer

Coterminal angles are found by adding or subtracting $360^\circ$ from the given angle. For $117^\circ$, adding $360^\circ$ gives $477^\circ$ and subtracting $360^\circ$ gives $-243^\circ$.
