Points D, E, and F are the midpoints of sides BC, CA, and B of triangle ABC, respectively, and CZ is an altitude of the triangle. If angle BAC = 71 degrees, angle ABC = 39 degrees, and angle BCA = 70, then what is angle EZD +  angle FZD in degrees?

I see one immediate problem here..... if BAC  = 17, ABC  = 39  and BCA = 70, the three interior angles of the triangle only sum to 126°  ... !!!
