Problem Statement

In a triangle ABCABC, the angle bisector of ABC^\widehat{ABC} meets [AC][AC] at DD, and the angle bisector of BCA^\widehat{BCA} meets [AB][AB] at EE. Let XX be the intersection of the lines BDBD and CECE where BX=3XD|BX|=\sqrt 3|XD| ve XE=(31)XC|XE|=(\sqrt 3 - 1)|XC|. Find the angles of triangle ABCABC.
