Question

in triangle ABD,AC intersects side DB such that AB is equal to BC and DC is equal to CD.find angle ABC

Answer 1

In a triangle there is 3 angles and the sum of all angle is 180 degree then AB intersect at the point c then the angle ABC and ADC is equal because intersecting point divide into two equal part .
AB is equal to BC then the half of angle BAD is 30 degree(each angle will be 60°) it is given that AB equal to BC . In angle ABC so it will be 30 degree.

Hope this will help you!
