please help ive been stuck on this question for so long i dont understand how to do this

Answer 1

a: 55°

Explanation:

The measure of arc NM is the same as the measure of the central angle that intercepts it: Q. The sum of the central angles of a circle is 360°, so ...

Q = 360° -120° -60° -65° -60° = 55°

The measure of arc NM is 55°.
