Answer:

No

Explanation:

You want to know if angles -345° and 2185° are coterminal.

Coterminal angles

Angles are co-terminal when their terminal sides are coincident. Each angle will have the same measure modulo 360°.

-345° / 360° = -1 remainder 15°

2185° / 360° = 6 remainder 25°

These angles have different values, modulo 360°, so are not co-terminal.
