Hey, I have a geometry exam tomorrow and I'm trying to complete a review packet from my teacher. I was doing fine until I reached the section on rhombi. I can't out for the life of me how to do this problem. Could you please help me? Please provide an explanation, if you can, as well. I've attached a general reproduction of the original diagram.

Thanks,

Alex!

If m<EBC = 132.6, find m<EBD.
