# Triangle question

I am not able to solve this question from chapter "Similar & Congruent Triangles" in my book.

Can some one help to calculate AC?

WAit! According to your question BD + DC = DC + ED = CE = BC. But triangle BDE would then be a straight line, if you remember the triangle inequality! –  Sawarnik Oct 13 '13 at 15:27

Hint: $\triangle ABC \sim \triangle CEB \sim \triangle BDE$.
