Title: Solving Similar Triangles 2

https://trello.com/c/0VrGwyhd

An exercise to show how to solve the angle bisector theorem using similar triangles. It demonstrates the AoPS technique shown at: http://www.artofproblemsolving.com/Wiki/index.php/Angle_Bisector_Theorem

Much borrowed from the angle_bisector_theorem.html exercise.
