Hello fellow users of AOPS, my name is ! As you can see I like math. That's why I'm here.
I have taken many math competitions, including the Canadian Gauss, Pascal and Cayley. I have also taken Canadian Intermediate Mathematics Examination, and the Math Challengers competition sponsored by the Canadian Math Challengers Society. I also have taken AMC 8, and this year I'm taking the AMC 10, as well as the COMC (Canadian Open Mathematics Challenge).
We can set coordinates for the points. and . The line 's equation is , line 's equation is , and line 's equation is . Adding the equations of lines and , the coordinates of is . Furthermore the coordinates is . Using the Pythagorean Theorem, the length of is , and the length of = The length of . Then Then the ratio Then and is and , respectively. The problem tells us to find , so
