What is the sum of the interior angles of a 20-sided polygon?
(20-2)*180
To find the sum of the interior angles of a polygon, you can use the formula:
Sum of interior angles = (n - 2) * 180 degrees,
where "n" represents the number of sides of the polygon.
In this case, you have a 20-sided polygon, so you can plug "n = 20" into the formula:
Sum of interior angles = (20 - 2) * 180
= 18 * 180
= 3240 degrees.
Therefore, the sum of the interior angles of a 20-sided polygon is 3240 degrees.
