    The sum of the angles in a polygon is given by \(\large 180(n-2) \) where 'n' is the number of sides.

    Yes, but why would you divide by 11?

    Unless I've lost my ability to count, there are 12 sides, soooo \(\ 180(12-2)=180(10)=1800 \)

    (180n–360) is the formula for the sum of the interior angles of a polygon

    If 'n' is the number of sides, then there are 12 sides, not 10. And that formula is the distributed form of \(\ 180(n-2) \)
