and you proved that because the angles of a parallelogram are equal? and that KF bisects both Angles K and F?

hmm i am really tired and not thinking straight but from what you have so far i think it is only a matter of using some theorem that i have forgotten because you know that MH is 9 which is similar to EM and that MJ is 4 which is similar to EM, but i dont rememeber anything about similarities.

Btw what level of math are you in? highschool geometry?
