Question 5 (i)
In the given figure, the arms of two angles are parallel. If $\Delta ABC={70}^{\circ }$, then find: $\angle DGC$

Answer 1

$\text{Given, AB || DE and BC is a transversal line and}\angle ABC={70}^{\circ }\because \angle DGC=\angle ABC\text{[Corresponding angles]}\therefore \angle DGC={70}^{\circ }$
