Answer:
AE = 70
Step-by-step explanation:
since triangle BDF bisects each side of triangle AEC, then triangle BDF is a medial triangle and the result is the following:
all four triangles are congruent (their sides are proportional)
sides that measure 25: BA, BC, DF
sides that measure 30: CD, DE, FB
sides that measure 35: FA, FE, BD
if FA = 35 and FE = 35 then AE = 70
