Find Rhombus Angles: 360º & 22º30

[Joostrea]

The angle between the diagonal and the side of the rhombus is 22º30’. Find rhombus angles.
Rhombus interior angles are 360º that much I know, but how do I find out the other angles?

 

[Alaskan Son]

Just remember that by definition, a rhombus is always going to be congruent on opposing sides of each diagonal. See if this helps you get started...

B=22º30’*2=45º
B=45º
D=45º

45º+C=180º
C=135º
E=135º

Did I do it right?
