What have you done so far to figure this out?

I have figured out angle ecf = 24

angle bec = 144

Not really sure on that though. - Oct 8th 2011, 10:02 AMFrameOfMindRe: Rectangle and Rhombus
That's correct.

To work out the remaining angles remember that all the sides of a rhombus are equal length, and that all the sides of an equilateral triangle are equal. What do you notice about the remaining triangles?
