Give an expression that generates all angles coterminal with the given angle. Let n represent any integer.
-$42 ^ { \circ }$
A) $42 ^ { \circ } + \mathrm { n } \cdot 180 ^ { \circ }$
B) $42 ^ { \circ } + \mathrm { n } \cdot 90 ^ { \circ }$
C) $42 ^ { \circ } + \mathrm { n } \cdot 360 ^ { \circ }$
D) $42 ^ { \circ } + \mathrm { n } \cdot 720 ^ { \circ }$

Angles are coterminal if they differ by a full rotation, which is $360^\circ$. Therefore, adding $360^\circ$ multiplied by any integer $n$ to the original angle $42^\circ$ generates all angles coterminal with $42^\circ$.
