What is the sum of the interior angles of a 21 gon?
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 3420 degrees
What is the interior angle of a 21 sided shape?
(n-2)*180 3420 degrees
What is the sum of the interior of an icosikaihenagon?
The sum is 3420 as the equation for every regular polygon is (n-2)*180 when n is number of sides
What is 3419 rounded to the nearest ten?
3420
Name three numbers between 0.33and0.34?
.3430 .3420 .3410
What is the sum of the interior angles of a 21 sided polygon?
180*(21-2) = 180*19 = 3420 degrees.
How many degrees is a 21 sided polygon?
To determine the total number of degrees of any polygon, you can use the equation y=180x-360, where x is the number of sides. In your case, it would be y = 180(21) - 360, which equals 3420 degrees.
How many sides does a polygon have if the sum of the interior angles is 3420?
It will have: (3420+360)/180 = 21 sides
What would be the interior angle of a 31 sides polygon?
That would depend if it's a regular or an irregular polygon but in both cases all the interior angles add up to 3420 degrees
What is the sum of the interior angles of a 21 gon?
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 3420 degrees
What is the sum of the interior angles of a polygon with 21 sides?
(n-2)*180 degrees where n is the number of sides. In this case, n = 21 so 19*180 = 3420 degrees.
the interior angle of a polygon with 21 sides?
So, the Sum of the interior angles for a 21 – sided polygon is equal to 3420°.
If a regular polygon measures 90 degrees what is the name of the polygon?
Right angle not polygon. (i'm not mad).
What is the sum of the interior angle measures of a 21-sided polygon?
The sum of the interior angles of a polygon is 2n - 4 right angles where n is the number of sides. When n = 21 then 2n - 4 = 42 - 4 = 38 right angles = 38 x 90 = 3420°. NOTE : If the polygon is a regular polygon then each interior angle measures 3420 ÷ 21 = 162.86°.
what would the name of the polygon if it measure 540 degrees?
A pentagon is a 5 sided polygon whose interior angles add up to 540 degrees
What is the name of polygon that has 40 degrees exterior angle?
Providing that it is a regular polygon then it is a nonagon which has 9 sides
What type of polygon has the sum interior angles of 3420?
The sum of angles of a regular polygon: (n - 2)180 = 3,420 180n - 360 = 3,420 add 360 to both sides; 180n = 3,780 divide both sides by 180; n = 21 Thus a 21-side regular polygon has the sum of interior angles 3,420 degrees.
