Question

Find the value of $x$ in each of the following figure, if $l||m$.

Answer 1

$\angle TOA=\angle ODE=110°$ ( corresponding angles since l and m are parallel )

$\Rightarrow \angle ODE+\angle ODC=180°$ ( m is a straight line )

$110°+x°=180°$

$\Rightarrow x°=70°$

Hence, the answer is $70°.$
