It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
It is a nonagon whose 9 interior angles add up to 1260 degees
The interior angles of a 1260 sided polygon add up to 226,440 degrees and its exterior angles add up to 360 degrees
A nonagon which has 9 sides
It is a 9 sided nonagon whose interior angles add up to 1260 degrees
(n-2)*180 = sum of interior angles of any polygon where n = number of sides. (9-2)*180 = 1260 degrees.
The total interior angles add up to 1260 degrees.
Sum of interior angles of a polygon = (2n - 4)right angles 1260 = (2n - 4) x 90 1260 = 180n - 360 900 = 180n n = 5, it is a pentagon

1260 degrees
A 9 sided nonagon has interior angles that add up to 1260 degrees
The interior angles of a 1260 sided polygon add up to 226,440 degrees and its exterior angles add up to 360 degrees
The interior angles of a 9 sided polygon add up to 1260 degrees
The sum of a regular polygon's interior angles is always equal to (n-2) * 180, where n is the number of sides in the polygon. Given that one exterior angle measures 40 degrees, we can find the interior angle by subtracting 40 from 180 degrees (since the exterior and interior angles are supplementary) to get 140 degrees. So, the sum of the interior angles of the regular polygon is 140 * n.
A nonagon which has 9 sides
The sum of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a polygon with 9 sides, the sum of the interior angles is ( (9 - 2) \times 180^\circ = 7 \times 180^\circ = 1260^\circ ). Each interior angle in a regular nonagon (9-sided polygon) would then be ( \frac{1260^\circ}{9} = 140^\circ ).
