Given: ∆dek, de = ek ef − ∠ bisector of ∠e m∠def = 44° dk = 16 find: kf m∠dfe

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.
