Question

in the adjoining figure find angle ACD, if ab =bc=ac
please give me the answer fast​

Answer 1

Answer:

In the above triangle AB = BC = AC

So ∆ABC is a equilateral triangle

Here angle ACD is exterior angle

In a triangle exterior angle = sum of two opposite interior angles and here all angles are 60°(Because sum of three angles of traingle is 180° and all the three sides are equal)

So exterior angle ACD = 60°+60° = 120°
