In fig. the value of angle $$q$$ is :


ANSWER

$$40^0$$


SOLUTION
From figure, we have
$$50^{\circ}+x+90^{\circ}=180^{\circ}$$  (Angles made on straight line)
$$\Rightarrow x+{ 140 }^{ \circ  }={ 180 }^{ \circ  }\\ \Rightarrow x={ 180 }^{ \circ  }-{ 140 }^{ \circ  }={ 40 }^{ \circ  }$$
Therefore, $$q=x$$   (Vertically opposite angles)
$$\Rightarrow q=40^{\circ}$$
