Answer:
Step-by-step explanation:
This arc has the same measurement as the central angle. The central angle is LON where O is the center of the circle. 
Point M forms an angle that is 1/2 the central angle when M is on the circumference and opposite the 150o angle. Therefore M is the vertex of a 75 degree angle. 
76x - 1 = 75       Add 1 to both sides.
76x = 76            Divide by 76
x = 1
