Using a protractor an 8 sided octagon angles will add up to 1080 degrees
Or use the formula: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
144 degrees
Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
The 14 interior angles add up to 2160 degrees
You cannot. An interior angle of a 16-sided polygon can have any value. However, IF the polygon is regular, then each of its exterior angles is 360/16 = 22.5 degrees. The interior angle, being a supplementary angle to the exterior angle, will be 180-22.5 = 157.5 degrees.
Method 1: Interior angles of a regular n-sided polygon total (2n - 4) right angles or 180n - 360 degrees. Each angle is therefore ((180 x 25) - 360)/25 ie 165.6 degrees. Method 2: EXterior angles of regular n-sided polygon = 360/n degrees, in this case 360/25 ie 14.4 degrees. Interior angle = 180 - exterior ie 180 - 14.4 = 165.6 degrees.
144 degrees
a 7 sided polygon is heptagon and the interior angle of it is 128.57 degrees.
to find the the exterior angle, divide 360 degrees by the number of sides. so the answer is 15 degrees.
This figure is a regular 12-sided polygon. Find m<4
Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
This figure is a regular 12-sided polygon. Find m<4
The interior angles of a 14 sided polygon add up to 2160 degrees
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.
To find the sum of interior angles for any N-sided polygon = N*180° - 360°Solve the equation: N*180° - 360° = 3060°, for N, and N = 19
The exterior angles of any polygon add up to 360 degrees
The 14 interior angles add up to 2160 degrees
