Mathematics


If $$P \parallel Q$$ and $$l \parallel m$$, then find the angle of $$x$$ if the triangle whose exterior angles are $$x$$ and $$150^o$$ is isosceles.


ANSWER

105


SOLUTION
Given that the exterior angles $$x$$ and $$150^o$$ of the triangle are isosceles.
Therefore, Both the angles are equal 

Hence, $$x=150^o$$
