Geometry Question

Hi I think I saw your previous thread, while this number correction is welcome, you still have to tell us exactly what you are looking for, the area of triangle ABC? (would need more info for that one) the length of AB?, the area of WXYZ? what exactly should we be trying to solve for?

I don't know why it won't let me write the numbers - but if it doesn't show up, I don't know what to do anymore. I'll try to write it out again. ACB = 90 degrees, and YC = 2XC. Find AB.

AB = 8*sqrt(30).
