Given a regular pentagon ABCDE.

Angle EAB = x + y

I have this formula:

x + y = (1/5)(180)(5-2)

But how do I write the reference of that?

What do you mean by that? – Eric Stucky Jul 24 '14 at 07:36
@EricStucky I mean something like angle sum of triangle or angles at a point etc. – Jamie Jul 24 '14 at 07:38
Sorry, that still doesn't clear things up for me. Are you saying you want a name for the formula? – Eric Stucky Jul 24 '14 at 08:19
