Answer:
303^(\circ)

Explanation:

The point
P lies in the fourth quadrant, so the angle is given by
360^(\circ)-\alpha, where
\alpha is the reference angle.

The reference angle is given by
\arctan \left(((√(7))/(4))/((√(3))/(4)) \right)=\arctan \left(\sqrt{(7)/(3)} \right).

This means
\theta=360^(\circ)-\arctan \left(\sqrt{(7)/(3)}} \right) \approx 303^(\circ).
