$\small\angle\hspace{1px}$PTS + 38$^\circ\!$ = $\small\angle\hspace{1px}$QSR + $\small\angle\hspace{1px}$PSQ = $\small\angle\hspace{1px}$QSR + $\small\angle\hspace{1px}$PQS = 2$\small\angle\hspace{1px}$QSR + $\small\angle\hspace{1px}$PRS = 2$\small\angle\hspace{1px}$QSR + $\small\angle\hspace{1px}$PTS so $\small\angle\hspace{1px}$QSR = 38$^\circ\!$/2 = 19$^\circ\!$.
