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).

-19x>-113

/-19    /-19

(flip the sign)

x<7

i can't do the greater than or equal to sign so just remember to add that in :)
