Question 112

In the given figure, two parallel lines l and m are cut by two transversal p and q. Determine the values of x and y .

Answer 1

From the given figure,

$x={110}^{\circ }\left[alternateinteriorangles\right]andy+{80}^{\circ }={180}^{\circ }[\therefore Suminterioranglesonthesamesideoftransversalis{180}^{\circ }]$

$\Rightarrow y={180}^{\circ }-{80}^{\circ }\Rightarrow y={100}^{\circ }$
