Answer:
106°
Step-by-step explanation:
The angle CAB is an inscribed angle of the arc mBC, so we have that:
mBC = 2*CAB
So we have that mBC = 2*37 = 74°
The segment AC is a diameter of the circle, so mAC = 180°
The ? angle is the arc mAB, which is the difference of mAC and mBC, so:
mAB = mAC - mBC = 180 - 74 = 106°
So the ? angle is 106°.
