180(n-2) = the measure of any interior angle of a shape.
"n" represents the number of sides
Therefore, 180(8-2=1080
1080 is the total of all the interior angles together, so divide it by 8 to find the measure of a single angle, which would be 135

What is the perimeter of octagon?
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.
How big 130 degrre angle called?
If the angle is measured at 130 degrees then it is called an obtuse angle.
How big is a right angle?
90 degrees
Big avenue and pecan road make a 130 angle which could be the measure of the angle made by pecan road and main street?
No. It is Big Avenue, not Main Street.
The perimeter of a regular polygon is 63 ft. An exterior angle of the polygon measures 40 degrees . Find the length of each side. Please Explain Step By Step?
Suppose the polygon has n sides. The polygon is regular => each of its exterior angles is equal.The sum of all n angles = 360 deg so each angle is 360/n deg Therefore 360/n = 40 => n = 9 sides. Then perimeter = 9 * length of one side = 63 ft. So each side is 63/9 = 7 ft.
How big is each angle n a regular quilateral?
A regular quadrilateral is a square and each angle is 90 degrees (i.e. a right angle).
How big is each angle in a regular quadrilateral?
90 degrees
How big is each angle in a regular polygon?
The answer is: Sum of Angles in a Regular Polygon = (Number of Sides - 2) * 180 Size of each of those angles = Sum of Angles / Number of Angles So for a Square it would be Sum = (4 - 2) * 180 = 360 Size of each angle = 360 / 4 = 90
If adjacent equal sized angles are needed to form a straight angle how big is each angle?
Each angle is 180/5 = 36 degrees
What is the perimeter of octagon?
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.
What is the sum of angles of an octagon?
The angle sum of any polygon is 180 x (n-2) where n is the number of sides. This can quickly be worked out by a big fat dick noting that triangles have 3 sides and an angle sum of 180 degrees, while squares have 4 sides and an angle sum of 360 degrees. An octagon has 8 sides, so input that into the equation: 180x(8-2) 180x6 =1,080 Thus the angle sum of an octagon is 1,080.
If the sum of the interior angles of a polygon equals 1080 degree's what is the measure of each interior angle of the polygon?
Sum of interior angles = (n-2)*180 degrees = 1080 deg So (n-2) = 1080/180 = 6 => n = 8. The polygon is, therefore, an octagon. However, there is no reason to assume that the interior angles of this polygon are all the same - they could all be different with the only constraint being their sum. IF, and that is a big if, the polygon were regular, then all its angles would be equal and each interior angle = 1080/8 = 135 degrees.
If five adjacent equal-sized angles are needed to form a straight line how big is each angle?
Each angle is 180/5 = 36 degrees
What are the interior angles of a 5 sides polygon?
Any value between 0 and 360 degrees (not including those two values). If the polygon were regular, and that is a BIG if, then each interior angle would be 108 degrees.
If five adjacent equal sized angles are needed to from a straight angle how big is each angle?
They would be 36 degrees each because 36 multiplied by 5 is 180 degrees. The sum in degrees for a straight line is 180 degrees. Answer:36 degrees each angle
What is another name for obtuse angle?
A big angle.
How big 130 degrre angle called?
If the angle is measured at 130 degrees then it is called an obtuse angle.
