In order to calculate angle PRS, we can use the following property of intersecting chords:


mPRS=(1)/(2)(PS+TQ)

So, calculating angle PRS, we have:


\begin{gathered} \text{PRS}=(1)/(2)(88+20)_{} \\ \text{PRS}=(1)/(2)(108) \\ \text{PRS}=54\degree \end{gathered}

Therefore the correct option is the third one.
