Exterior angle Theorem (need a full recap of how this theorem works.)

[Nathaniel Barnhill]

Ok, so my teacher did a bloody terrible job of teaching this subject so I really need a full recap of how this theorem works. I am having trouble when it comes to the problems where it only shows one equation like for example 12x+6. Feel free to ask me if you don't understand what I am asking.
Thanks

The sum of the exterior angles of a closed polygon is 360º. What else is needed.

BTW, your question contains almost no useful information. Please do better.

Please state the entire problem, so we can tell what you are asking about. 12x+6 isn't even an equation! (It's an expression.) But where is it? What else is said about the figure? And was tkhunny right about which theorem you mean by "exterior angle theorem"? Is it this one, instead?

When you reply with the previously-requested information, please also include what you mean by the "Exterior Angle Theorem", because I think we may be experiencing some confusion about which theorem you actually mean...? Thank you!
