Question 188469: What is the sum of the measures of the interior angles of a 3x-gon?
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! If a "3x-gon" has 3 sides, it's 180 degrees.
Total of internal angles of a polygon with n sides is:
(n-2)*180
--------
If a 3x-gon is something else, you'll have to explain what it is.
-----------------
In general, if it has 3x sides, the total is:
(3x-2)*180
