What is the angle sum of a polygon with 9 sides?
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
If the sum of the interior angle measures of a polygon is 1260 how many sides does the polygon have?
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
What regular polygon has the sum of its interior angles add up to 1260?
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
What polygon has interior angles adding up to 1260?
It is a nonagon whose 9 interior angles add up to 1260 degees
What is a polygon with 1260 degrees?
It is a 9 sided nonagon whose interior angles add up to 1260 degrees
One exterior angle of a regular polygon measures 40 What is the sum of the polygons interior angle measures?
1260 degrees
What is the angle sum of a polygon with 9 sides?
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
One exterior angle of a regular ploygon measures 40 what is the sum of the polygon's interior angles measures?
1260 degrees
What is the name of polygon that has 40 degrees exterior angle and have an interior angles has 1260 degrees?
It has 9 sides and is called a nonagon
One exterior angle of a regular polygon measures 40 What is the sum of the polygon's interior angle measures?
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.
If the sum of the interior angle measures of a polygon is 1260 how many sides does the polygon have?
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
How many sides does a polygon have if the interior angles equal 1260?
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
What is the sum of the polygons interior angle if the exterior angle measures 40 degrees?
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.
What is the measure of each interior angle of a regular nonogon?
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.
What regular polygon has the sum of its interior angles add up to 1260?
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
How do you calculate the angle sum of a 9-side polygon?
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
What polygon has interior angles adding up to 1260?
It is a nonagon whose 9 interior angles add up to 1260 degees
