A) \[{{126}^{o}}\]
B) \[{{130}^{o}}\]
C) \[{{90}^{o}}\]
D) \[{{180}^{o}}\]
Correct Answer: A
Solution :
Let \[a=2x\]and \[b=3x\] Now, XOY is a straight line. \[\therefore \]\[2x+3x+{{90}^{o}}={{180}^{o}}\] \[\Rightarrow \]\[5x={{90}^{o}}\Rightarrow x={{18}^{o}}\] \[\therefore \]\[\angle XON=\angle MOP+\angle POY\] (vertically opposite angles) \[{{36}^{o}}+{{90}^{o}}={{126}^{o}}.\]You need to login to perform this action.
