find the sum of the measures of the interior angles of a 13-gon
To find the sum of the measures of the interior angles of a 13-gon, you can use the formula:
Sum of interior angles = (n - 2) * 180 degrees
where n is the number of sides of the polygon.
Substituting n = 13 into the formula:
Sum of interior angles = (13 - 2) * 180 degrees
Simplifying the expression:
Sum of interior angles = 11 * 180 degrees
Finally, calculating the sum:
Sum of interior angles = 1980 degrees
To find the sum of the measures 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 13-gon, which means it has 13 sides. Applying the formula:
Sum of interior angles = (13 - 2) * 180 degrees
= 11 * 180 degrees
= 1980 degrees
So, the sum of the measures of the interior angles of a 13-gon is 1980 degrees.
the sum of the interior angles of an n-gon is
180(n-2), so ....
