Final answer:
The formula s=180(n-2) calculates the sum of interior angles of an n-sided polygon. 'n' stands for the number of sides in the polygon, and 180 is a constant in geometry related to angles. The sum of interior angles of a 3-sided polygon (triangle) would be 180(3-2) = 180 degrees.
Step-by-step explanation:
The given formula, s=180(n-2), is used to calculate the sum of the interior angles of an n-sided polygon. In this formula, 'n' represents the number of sides of the polygon. The '180' is a standard value in geometrical calculations involving angles of polygons. Subtracting 2 from 'n' and multiplying the outcome by 180 gives you the sum of the interior angles. For instance, a triangle, which is a 3-sided polygon, the sum of the interior angles will be 180(3-2) = 180 degrees.
