empty document. We don't really like having to download docs either. Can you just type it in, or take a screen snapshot and crop it down and post the image?

Ok, It's all about the similar triangles.

Just note that ADE, ACB, EFB are all similar triangles and that

DE = CF, DC = EF

play around with the ratios given by the similar triangles and substitute in those equalities above and you'll get it.

Yell back if not.
