Question
In ΔABC, ∠B = 60° and ∠C = 40°; AD and AE are respectively the bisector of ∠A and perpendicular on BC. The measure of ∠EAD is:
Answer: Option C
As we know
$$\eqalign{
& \angle EAD = \frac{{\angle B - \angle C}}{2} \cr
& \angle EAD = \frac{{60 - 40}}{2} \cr
& \angle EAD = {10^ \circ } \cr} $$
