    |dw:1328421140102:dw| from this we know that: x+y = 90 sin(x) = BC/2 cos(y) = BC/2

    haha i don't think you do, we need more info about where point B is located you could just pick a value for x,y as long as they add up to 90? unless there is something i'm not seeing

    sin(x)=cos(y), 0<x,y<90
