1997 Pascal Problem 20

A beam of light shines from point S, reflects off a reflector at point P, and reaches point T so that PT is perpendicular to RS. Then x is

\textbf{(A)}\ 26^\circ\quad \textbf{(B)}\ 32^\circ\quad \textbf{(C)}\ 37^\circ\quad \textbf{(D)}\ 38^\circ\quad \textbf{(E)}\ 45^\circ

If there are no answer choices shown, enter a numerical answer.
