Problem
In triangle Points and are located on such that The circumcircle of cuts at respectively. If then the ratio can be expressed in the form where are relatively prime positive integers. Find
Solution
By the Power of a Point Theorem on , we have . By the Power of a Point on , we have . Dividing these two results yields . We are given and so . Then the previous equation simplifies to . Hence
