Question : In $\triangle ABC$, $\angle B=60°$, $\angle C=40°$. AD is the bisector of $\angle A$ and AE is drawn perpendicular on BC from A. Then the measure of $\angle EAD$ is:
Option 1: $40^{\circ}$
Option 2: $30^{\circ}$
Option 3: $10^{\circ}$
Option 4: $80^{\circ}$
Correct Answer: $10^{\circ}$
Solution : Let AD be the angle bisector and AE be the perpendicular. ⇒ $\angle$BAC + $\angle$ABC + $\angle$ACB = $180^{\circ}$ ⇒ $\angle$BAC + $60^{\circ}$ + $40^{\circ}$ = $180^{\circ}$ ⇒ $\angle$BAC = $180^{\circ}$ – $100^{\circ}$ = $80^{\circ}$ ⇒ $\angle$BAD = $\frac{80^{\circ}}{2}$ = $40^{\circ}$ In $\triangle$AEB, ⇒ $\angle$BAE
