-$126 ^ { \circ }$
A) $486 ^ { \circ } ; - 234 ^ { \circ }$
B) $306 ^ { \circ } ; - 54 ^ { \circ }$
C) $486 ^ { \circ } ; - 54 ^ { \circ }$
D) $396 ^ { \circ } ; - 144 ^ { \circ }$

Quizplus · Accepted Answer

To find coterminal angles, add or subtract multiples of $360^\circ$. For $126^\circ$, adding $360^\circ$ gives $486^\circ$ and subtracting $360^\circ$ gives $-234^\circ$.
