Question

In figure if AE ll DC and AB = AC, find the value of angle ABD.
​

Answer 1

Answer:

130°

Step-by-step explanation:

angle a =50

angle a = angle ACB =50°

triangle abc is iso.triangle with ab=ac

hence angle abc=angle acb

angle acb =50°

angle acb + angle ABD=180°

hence angle ABD=180-50

angle ABD = 130°
