Essentially, what we need to do here is prove that BE=EC, BE=CB, and.or CE=BC therefore making it isosceles. With ∠AEC=∠DEB, we know AE=DE, so EC=EB (the points go in order). Therefore, as EC=EB, BEC is isosceles (it has at least 2 equal sides).

Feel free to ask further questions!

Nanci needs at least $140 for her vacation this summer. She already has $25 and she is selling homemade bracelets for $3.00 each

Please look at the screenshot below, for some reason Brainly won't let me post my answer.

What I mean about "not fully written" is its impartial. It didn't ask us something like "find how many bracelets she needs to sell"
