Question

In the adjoining figure, if line $l\parallel m$ and line $n$ is the transversal, what is the value of $x$

• A. ${65}^0$
• B. ${50}^0$
• C. ${41}^0$
• D. ${130}^0$

Answer 1

The correct option is D ${130}^0$

$y={50}^{\circ }$ (Alternate angle)

$x+y={180}^{\circ }$ (Sum of corresponding angles is always ${180}^{\circ }$)

$x+{50}^{\circ }={180}^{\circ }$

$x={130}^{\circ }$.
