Urgent help with basic geometry problem?

I apologize for the lack of a diagram. Points A (upper point), B (right point), C (lower point), & D (left point) would form a rhombus. Lines DB and AC should be intersecting point D, and in turn, bisecting angles ABC, BCD, CDA, & DAB.
I'd like to answer the question "In rhombus ABCD the diagonals intersect at point E. ABC is four times the measure of angle BAD. Find the measure of angle EBC." I would really appreciate the help. Thanks!
