How many sides on a polygon with the sum of the interior angles is 6840?

To find the number of sides on a polygon with a sum of interior angles of 6840 degrees, we can use the formula: (n-2) * 180 = 6840, where n represents the number of sides. Solving for n, we get n = (6840 / 180) + 2 = 38. Therefore, the polygon has 38 sides.

What is the sum of a interior angle of a polygon with 38 sides?

Sum of interior angles of a 38 sided polygon: (38-2)*180 = 6480 degrees

What is the number of sides of a regular polygon if one angle measures 171 degrees?

The formula to find the sum of the angles of a polygon is: 180(n - 2) Since we know that one angle of this regular polygon is 171 degrees, we can find what kind of polygon it will be, using the formula: 180(n - 2) = 171n 180n - 360 = 171n 180n - 171n = 360 9n = 360 n = 360/9 n = 40 Thus the polygon is a 40-sided polygon. Check: 180(40 - 2) = 180(38) = 6840, which is the sum of the angles of the polygon. 6840/40 = 171 degrees, which is the measure of one of the angles of that polygon .

What is the answer to x-25 equals 38?

x - 25 = 38 x - 25 + 25 = 38 + 25 (add 25 to both sides) x = 63

How do you solve the equation 5n - 7 equals 38?

To solve the equation 5n - 7 = 38, do whatever you do to one side of the equals sign to the other. So, add 7 to both sides. 5n = 38. Now divide both sides by 9. 5 = 9. To check your answer, replace the n with 9 and solve the equation. 5 x 9 - 7 = 38. Do the multiplacation first. 45 - 7 = 38. 38 = 38. The answer is correct.

What is a 38 sided polygon called?

A 38-sided polygon is called a triacontakaioctagon. The naming convention for polygons follows the Greek numerical prefixes for the number of sides, in this case "tri" for 3 and "contakai" for 10, along with the suffix "-gon" for polygon. Therefore, a 38-sided polygon is a triacontakaioctagon.

How many triangles does a 38 sided polygon contain?

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°.

How many sides do 2 nonagons and 2 decagons have in all?

What are the sum of the interior angles of a polygon with 40 sides?

The sum of the interior angles of a polygon can be calculated using the formula: [ \text{Sum of interior angles} = (n - 2) \times 180^\circ ] where (n) is the number of sides of the polygon. For a polygon with 40 sides ((n = 40)): [ \text{Sum of interior angles} = (40 - 2) \times 180^\circ = 38 \times 180^\circ = 6840^\circ ] Thus, the sum of the interior angles of a polygon with 40 sides is **6840 degrees Read more....tinyurl com/22enuvst

One pair of corresponding sides of two similar polygons measures 12 and 15 The perimeter of the smaller polygon is 30 Find the perimeter of the larger?

The perimeter of the larger polygon will have the same ratio to the perimeter of the smaller as the ratio of the corresponding sides. Therefore, the larger polygon will have a perimeter of 30(15/12) = 37.5, or 38 to the justified number of significant digits stated.

What degrees is each interior angle of a 38 sided polygon?

What is the number of sides of a regular polygon if one angle measures 171 degrees?

The formula to find the sum of the angles of a polygon is: 180(n - 2) Since we know that one angle of this regular polygon is 171 degrees, we can find what kind of polygon it will be, using the formula: 180(n - 2) = 171n 180n - 360 = 171n 180n - 171n = 360 9n = 360 n = 360/9 n = 40 Thus the polygon is a 40-sided polygon. Check: 180(40 - 2) = 180(38) = 6840, which is the sum of the angles of the polygon. 6840/40 = 171 degrees, which is the measure of one of the angles of that polygon .
