Question

Given: ∆DEK, DE = EK

Answer 1

DFE=46
kf=8

because ef is bisector that means e is 44+44=88 since the triangle is isosceles the other angles are equal 180-88=92 so each angle is 46. since 46+44=90 the smaller triangle def and efk are right. so I think that makes ef the perp bisector so that de=FM so kf=1/2dk.
