A) \[80{}^\circ \]
B) \[40{}^\circ \]
C) \[100{}^\circ \]
D) \[25{}^\circ \]
Correct Answer: A
Solution :
\[\because \] \[\angle OBD=50{}^\circ \] \[\because \] \[\Delta OBD,OB=OD=r=\]radius \[\therefore \,\,\,\,\] \[\,\angle BOD=180{}^\circ -(50{}^\circ +50{}^\circ )=80{}^\circ \] \[\therefore \,\,\,\,\] \[\angle AOC=\angle BOD=80{}^\circ \]You need to login to perform this action.
