What is the measure of an exterior angle of a regular polygon of 12 sides?
Exterior angle of ANY regular n-sided polygon is 360/n degrees, in this case 360/12 ie 30o
How many sides does a regular polygon have if the measures of each exterior angle equals 12 degrees?
The regular polygon whose exterior angle measure is 12 degrees, has 30 sides (360/12, since the exterior angles on any polygon always add up to 360 degrees).
What polygon has the interior angles of 150 degrees?
A regular 12 sided polygon each interior angle measures 150 degrees
Calculate number of sides of a regular polygon has if an interior angle is five times the size of an exterior angle?
Suppose the interior angle is x degrees. Then the exterior angle is 180 - x degrees. x = 5*(180-x) = 900 - 5x So 6x = 900 so that x = 150 degrees. So exterior angle = 30 degrees. If the polygon has n sides (and n angles) the sum of its exterior angles is 30*n But the exterior angles of a polygon add to 360 degrees So 30*n = 360 so that n = 12. ANSWER: 12 sides.
What is the total of all the angles in a 12 sided shape?
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees so all together 2160
What is the measure of an exterior angle of a twelve sided polygon?
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
What is the sum of the angles of a 12-sided polygon?
Exterior angles = 360 degrees Interior angles = 1800 degrees
What is the size of all the exterior angles of a regular 12 sided polygon?
30 degrees
What is the exterior sum of angles in a dodecagon?
The exterior sum of angles for any polygon is always 360 degrees.The sum of the exterior angles of a 12 sided dodecagon is 360 degrees
How much is the exterior angle of an 12 sided polygon?
Like all polygons the exterior angles add up to 360 degrees
What is are the angles on a 12 sided polygon?
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees
What is the measure of an exterior angle in a 12 sided polygon?
Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
What is the angle sum for a 12 sided polygon?
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees
How many sides does a regular polygon if each exterior angle is 12 degrees?
Sum of exterior angles = 360 degrees If each one is 12 deg there must be 360/12 = 30 of them. So it is a 30 sided polygon.
What is the number of sides of a regular polygon with each interior angle equal to 150 degrees?
It is a 12-sided polygon, a dodecagon.The exterior angle for a polygon of n sides is 360/n.Each of the interior angles are supplementary angles (180-exterior angle).(180-150) n = 36030n = 360n = 12
What does a tweleve sided polygon contain?
!2 exterior angles that add up to 360 degrees 12 interior angles that add up to 1800 degrees
What is the sum of the measure of the interior angles of a 12-sided polygon?
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
