A) \[{{60}^{o}}\]
B) \[{{90}^{o}}\]
C) \[{{120}^{o}}\]
D) None of above
Correct Answer: C
Solution :
\[\Delta ABC\]is equilateral \[\Delta \]. \[\therefore \] \[\angle A=\angle B=\angle C={{60}^{o}}\] So, \[\angle BOC=2\angle A=2\times {{60}^{o}}={{120}^{o}}\]You need to login to perform this action.
