Question 135202
Insufficient information.  Are you talking about a 10 sided polygon and a 7 sided polygon, or a 100 sided polygon and a 103 sided polygon?  Is the "first" polygon the one with more sides?  Are they regular polygons?


In general, the sum of the interior angles of a regular n-gon is given by:


{{{(n-2)*180}}} degrees


The ratio of the sum of the angle measures in two polygons, one an n-gon and the other an (n-3)-gon, would be:


{{{(((n-3)-2)*180)/((n-2)*180)=(n-5)/(n-2)}}}


I'm not sure if any of this helps.
