Triangle ABC is an isosceles right triangle with a right angle at A. Segments BD and BE trisect angle ABC. What is the degree measure of angle BEA?

Triangle ABC is an isosceles right triangle with a right angle at A ie A = 90^{0}. B = C = 45^{0}.

B = 45^{0} and it is trisected into 3 equal angles of 15^{0}. BEA = 15^{0}.

ABE = 15º

BEA = 75º

Geometry is a lesson that I really had a hard time with, thanks for your answer.
