In the given figure, sides \( Q P \) and \( R Q \) of \( \triangle P Q R \) are produced to points \( S \) and \( T \), respectively. If \( \angle S P R=135^{\circ} \) and \( \angle P Q T=110^{\circ} \), then \( \angle P R Q \) equals
(a) \( 35^{\circ} \)
(b) \( 45^{\circ} \)
(c) \( 55^{\circ} \)
(d) \( 65^{\circ} \)
