A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[60{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: A
Solution :
\[OA=OB=AB\] Hence \[\Delta \,\,OAB\] is equilateral so that \[\angle AOB={{60}^{o}}\] Hence the angle subtended by AB on the longer side of the circle \[=\frac{1}{2}\angle AOB={{30}^{o}}\]You need to login to perform this action.
