The sum of the interior angles of a polygon can be found using the formula ( (n-2) \times 180^\circ ), where ( n ) is the number of sides of the polygon. For a 20-gon, ( n = 20 ), so the sum of the interior angles is ( (20-2) \times 180^\circ = 18 \times 180^\circ = 3240^\circ ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
