A nonagon or a polygon with 9 sides.
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
We solve the equation for n... since the sum of the interior angles is 180(n-2) where n is the number of sides of the polygon. So we have: 180(n-2)=1260 n-2=7 n=9 So 9 sides
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
It is a 9 sided nonagon whose interior angles add up to 1260 degrees
1260
1260 degrees

1260 degrees
It has 9 sides and is called a nonagon
We solve the equation for n... since the sum of the interior angles is 180(n-2) where n is the number of sides of the polygon. So we have: 180(n-2)=1260 n-2=7 n=9 So 9 sides
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
Providing that it's a regular polygon then its interior angles will add up to 1260 degrees with each of its 9 interior angles measuring 140 degrees.
Method 1: Exterior angle of n-sided regular polygon is 360/n degrees, in this case 40 so interior angle is 180 - 40 ie 140 degrees; Method 2: Interior angles of regular n-sided polygon total 180n - 360 degrees, in this case 1260 degrees so each angle is 1260/9 ie 140 degrees.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
The formula for calculating the interior angles for any polygon is:- (number of sides -2)*180 = sum of interior angles So: (9 -2)*180 = 1260 degrees
It is a nonagon whose 9 interior angles add up to 1260 degees
