Question

In figure if AE || DC and AB = AC, find the value of ∠ABD.

a)130°
b)110°
c)120°
d)70°​

Answer 1

Answer:

130

Step-by-step explanation:

opposite angle of linear pair

Answer 2

Answer:

Angle A will be 50 degree (vertically opposite angle)

Angle A is equal to angle C (alternate angles)

Angle ABC is equal to angle ACB ( an isosceles triangle if has two sides equal then their angles will also be equal ) = 50°

Angle B+50° = 130°

so angle B will be 130°
