Answer:
3060°
Explanation:
If a body is made up of 19 sides we can find sum of the interior angles using the relationship below;
Sum of interior angles = (n-2) x 180
n = number of sides = 19
So, the sum of interior angles;
Sum of interior angles = (19 -2) x 180
Sum of interior angles = 17 x 180 = 3060°
