How do I find the interior angles of an irregular polygon WITH one external angle? I have an image as an example, but Jiskha won't allow internet addresses. What do I do?

if the polygon is irregular, no joy.

All you know is that at each vertex the sum of the interior/exterior angles is 180°

This didn't help, and I still am confused.
Sorry for being negative if I am being :)
