A) \[90{}^\circ \]
B) \[60{}^\circ \]
C) \[30{}^\circ \]
D) None of these
Correct Answer: B
Solution :
[b] In \[\Delta PRQ,\] |
\[\angle PRQ=90{}^\circ \][angle in semi -circle] |
and \[\angle RQP=30{}^\circ \][opposite angle] |
In \[\Delta PRQ,\] |
\[\angle PRQ+\angle RPQ+\angle RQP=180{}^\circ \] |
\[\angle RPQ=180{}^\circ -120{}^\circ =60{}^\circ \] |
