Question

Angle ABC as shown in the diagram given below equals

Answer 1

As both the triangle are equilateral triangle.. So each angle = 60
In triangle ABC
Angle BAD = angle ABD = angle BDA= 60
Similary in ∆BCD
Angle BCD = angle CBD = angle CDB = 60

Angle ABC = angle ABD + angle CBD
Angle ABC = 60 +60 =120

Answer 2

Since , all sides are equal so these are equilateral ∆

so. each angle is 60 °

now , < ABC = < ABD + DBC

=> 60° +60°

=> 120°

hope it help you !!
