In a circle, if PQ is the diameter of the circle and R is on the circumference of the circle, such that \[\angle PQR=30{}^\circ \] then \[\angle RPQ\] =?
A) \[90{}^\circ \]
B) \[60{}^\circ \]
C)\[30{}^\circ \]
D)\[45{}^\circ \]
Correct Answer:
B
Solution :
\[\therefore \] PQ is a diameter \[\Rightarrow \] \[\angle \]PRQ \[= 90{}^\circ \left( An angle in a semicircle is 90{}^\circ \right)\] \[\angle \]RPQ =\[180{}^\circ - \left( 90{}^\circ + 30{}^\circ \right)\]= \[\]
