The sum of the interior angles in the 18-sided polygon is 2880 degrees option (C) is correct.
What is a regular polygon?
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
We have a 18-sided polygon.
As we know the sum of the interior angle is given by:
= 180(n - 2)
n = 18
= 180(18 - 2)
= 180(16)
= 2880 degrees
Thus, the sum of the interior angles in the 18-sided polygon is 2880 degrees option (C) is correct.
