EXERCISE 5.2

Find the value of $x$ in the following figure if $l\mathrm{}\left|\right|\mathrm{}m.$ {write only numerical value without degrees symbol}

Find the value of $x$ in the following figure if $l\parallel m.$

In the given figure, the arms of two angles are parallel. If $\mathrm{\angle }\mathrm{A}\mathrm{B}\mathrm{C}\mathrm{}=\mathrm{}{70}^{\mathrm{o}}$, then find $\mathrm{\angle }\mathrm{D}\mathrm{G}\mathrm{C}$ (without degree).

In the given figure, the arms of two angles are parallel. If $\mathrm{\angle }\mathrm{A}\mathrm{B}\mathrm{C}\mathrm{}=\mathrm{}{70}^{\mathrm{o}}$, then find $\mathrm{\angle }\mathrm{D}\mathrm{E}\mathrm{F}$.{write only numerical value without degrees symbol}
