Identify the angle P as MPN.

The angle between a tangent (TM) and a chord (MN) through the point of contact (M) is equal to the angle in the alternate segment subtended by the chord.

$$\hat{P} = \angle M_1$$ $$\hat{P} = 66^\circ$$

Reason: Angle between tangent and chord is equal to the angle in the alternate segment.

$$\boxed{\hat{P} = 66^\circ}$$
