    The measure for each interior angle of a regular 15-gon would be "156". Equation: (n-2)180/15 n= the number of sides There is 2,340 degrees in a 15 gon, so you divide that by 15 which equals 156.

    156, like it says in my equation.

    the sum of all EXTERIOR angles in any polygon is 360 The interior angle is the complement of that

    To do this you have to do 360/15, that answe will give you each angle

    @hybrik that gives the exterior angle - NOT the interior

    another way to do this is to use the fact that the sum of all the exterior angles of a polygon add up to 360 so each internal angle in a regular polygon = (180 - (360/n)) where n = number of sides

    You have to do 2340/15 as Flvs said @MrNood
