Question
What is the sum of the interior angles of a 20-sided figure?
Solution
The sum of the interior angles of any polygon can be found using the formula (n-2) * 180, where n is the number of sides.
Step 1: Identify the number of sides (n). In this case, n = 20.
Step 2: Subtract 2 from the number of sides. So, 20 - 2 = 18.
Step 3: Multiply the result by 180. So, 18 * 180 = 3240.
Therefore, the sum of the interior angles of a 20-sided figure is 3240 degrees.
