If not, prove why not. If it's possible, how can you do it?

Consider a parabolic mirror with vertex \(O\). A light ray originating from focus \(S\) of the parabola, strikes the mirror at a point \(P\) such that it gets deviated by \(30^{\circ}\) after reflection.

Now, if we draw a tangent at point \(P\) to the same parabola, it intersects the tangent at vertex at point \(Q\). Find \(\angle OSQ\) (in degrees).

The image is not drawn to scale.

**Note:** The parallelogram has no special properties as of a rectangle or a rhombus.
