You can put this solution on YOUR website! what is the total number of degrees in a 22-gon?
--------
When you have a big number like 22 try looking at smaller numbers to
see if you can find a pattern.
-----------
3-gon has 180 degrees
4-gon has 360 degrees
5-gon probably has 540 degrees
etc.
Now look for a pattern:
3 sided has 1*180
4-sided has 2*180
5-sided has 3*180
---
10-sided probably has 8*180
-----
22-sided probably has 20*180 = 3600 degrees
