In triangle ABC, angle c = 90 degrees, D is a point on edge BC, and angle ADC = 45 degrees Let de be perpendicular to AB and E, and AE: be = 10:3 If de = root 2, it is the length of bisector CF of angle C F is on AB, of course

Is it 6 / 5 times root 13
Make am parallel CF cross BC extension line at m through point a
