A) \[{{70}^{o}},\,\,{{80}^{o}}\]
B) \[{{70}^{o}},\,\,{{70}^{o}}\]
C) \[{{80}^{o}},\,\,{{80}^{o}}\]
D) None of these
Correct Answer: A
Solution :
It is given at ABCD is a cyclic quadrilateral, We know that exterior angle of a cyclic quadrilateral is equal to interior opposite angle. \[\therefore \]\[\angle BCX=x={{70}^{o}}\] Also, \[\angle ADX=y={{80}^{o}}\]You need to login to perform this action.
