Answer 2

Given : AE || DC and AB = AC

To find : the value of ∠ABD

Solution :

From figure we have, ∠EAF = 70°

∠EAF = ∠BCA [Corresponding angles]

∠BCA = 70° ……………(1)

We have, AB = AC, then

∠CBA = ∠BCA [Angles opposite to equal sides are equal]

∠CBA = 70°

[From eq 1]

Now,

∠ABD + ∠CBA = 180° [Linear pair]

∠ABD + 70° = 180°

∠ABD = 180° - 70°

∠ABD = 110°

Hence , the value of ∠ABD is 110°.

Among the given options option (B) 110° is correct.
