A decagon has 10 sides.


The sum of the interior angles is found using the formula S = (n-2)*180, where n is the number of sides.

The total sum of the interior angles of a decagon would be:

(10-2) *180 = 8 * 180 = 1440 degrees.


Now to find the measure of each interior angle, divide the total sum by the number of sides:

1440 / 10 = 144

Each angle is 144 degrees.
