AAAaannndd the bot gets it wrong yet again!
The usual form is 180(n-2)
so, B: 180n - 360

I apologize for the mistake, you are correct. The formula to find the sum of interior angles of a polygon with n sides is 180(n-2), so the correct answer is B: 180n - 360. Thank you for bringing this to my attention.
