160 degrees. The sum of all interior angles in a N-sided polygon = (N-2)*180°
If the polygon is regular, then divide by N, so each angle is (1-2/N)*180°
Additional Information:-
The exterior angles of any polgon add up to 360 degrees. So if it is a regular polygon simply divide the number of sides into 360 which will give each exterior angle and to find its interior angle is: 180 - exterior angle.
In this case: 360/18 = 20 degrees exterior angle.
180 -20 = 160 degrees interior angle.

What is the rule to get the number of sides of a regular polygon when given the interior angle?
180-interior angle = exterior angle 360/exterior angle = number of sides
What is the measure of one interior angle of a regular polygon with nine sides?
Each interior angle of a regular nonagon measures 140 degrees.
If the measure of one interior angle of a regular polygon is 90 degrees how many sides does the polygon have?
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
What is the interior angle of a regular polygon has 19 sides?
it is 4329
What is the measure of an interior angle that has a regular polygon with 20 sides?
Each interior angle will measure 162 degrees
What is the measure of an interior angle 3 of a regular polygonwith 15 sides?
Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees.
