Question

In the figure, find the value of $x$ for which the lines $l$ and $m$ are parallel.

• A. ${136}^o$
• B. ${44}^o$
• C. ${46}^o$
• D. ${134}^o$

Answer 1

The correct option is A ${136}^o$

Given, $l\parallel m$
$\angle x$ and ${44}^{\circ }$ are co interior angles. Sum of the co - interior angles is ${180}^{\circ }$.
Hence, $\angle x+44=180$
$\angle x={136}^{\circ }$
