From the picture above, it's safe to assume that 2x+x=90 and x=30 degrees. Now, angle CED has angle C equal to 2x and angle D equal to 2x. So, if we substitute x=30, we get angle C is 60 degrees and angle D is 60 degrees. Hence, angle E is also 60 degrees.

It is safe to assume 2x+x=90 as the diagonals of a rectangle bisect eachother so BE=EA and since EBA=2X
EAB=2X
hence,2x+x=90

@truplayer256,

Thanks for your explanation.

Can you please explain how angle C and D are equal to 2x?

@truplayer256,

Thanks for your explanation.

Sure, if you look at the picture, you can clearly see that angle C is equal to angle B and angle D is equal to angle A. Since angle B equals 2x, angle C also equals 2x and the same goes for angle D.
