If $/ \| m$, What is $\angle x$ ?
If $/ \| m$, What is $\angle x$ ?
✓
Answer
Given, $l \| m$ and $t$ is a transversal.
We know that the sum of pairs of interior angles on the same side of the transversal is supplementary.
$
\begin{array}{lrl}
\therefore \angle x+70^{\circ}=180^{\circ} \\
\Rightarrow \angle x=180^{\circ}-70^{\circ} =110^{\circ}
\end{array}
$
