I'm solving some practice problems to prepare for a competitive exam . Here is one which I'm trying to do for some time but still haven't found a solution to :
"In the given figure , ∠ABC = 2∠ACB and AB=DC .Also , AD is the bisector of ∠BAC . Find ∠ABC "
Here is the drawing I made :
Note that I want to find the numerical value of ∠ABC in degrees.
Since AB and DC are sides of different triangle , I don't know how to begin.
Also since none of the angles is known , how can I find the value of angle?
