    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.
