This question is much harder than it looks. I tried for a very long time but could not solve it.

Let AD be the angle bisector of angle A in triangle ABC. Given that AB+AD=CD and AC+AD=BC, find the angles of triangle ABC.

Sorry I understand now. I tried a ton of law of cosines bashing and representing the lengths in terms of the sides of the triangle but I could not find a clean way to find the angles of the triangle.
