1800° is the sum of interior angles of a polygon having 12 sides.
Step-by-step explanation:
As we know that all the sides, as well as, interior angles of a polygon are congruent.
Number of sides/angles in a polygon = 12
To find,
Sum of interior angles of a polygon = (n - 2) * 180
As we know, n = 12
∵ (12 - 2) * 180
= 1,800°
Thus, the sum of all the interior angles of a polygon is equaled to 1800 degrees.
