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 degrees
Well, darling, the angle sum of a polygon with 9 sides is 1260 degrees. Each interior angle of a regular nonagon measures 140 degrees. So, if you add up all those interior angles, you get 1260 degrees. Math doesn't have to be a drag, honey!
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
1260 degrees
It has 9 sides and is called a nonagon
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.
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
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
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.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 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 nonagon whose 9 interior angles add up to 1260 degees
