Find the measure of one exterior angle of a regular hexagon?
Hexagon has 6 sides so 360/6 = 60 degrees interior angle therefore exterior angle = 360 - 60 = 300 degrees
What is the measure of one interior angle of a regular 13 gon?
Each interior angle measures: 152o 18' 27.69''
How many sides does a regular polygon have if the measure of one interior angle is 150?
if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
How many sides does a regular polygon have if the measure of each exterior angle is equal to 15?
Sum of exterior angles = 360 degrees. If each one is 15 degrees then there must be 360/15 = 24 of them.
One exterior angle of a regular polygon measures 30 what is the sum of the polygons exterior angle measures?
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
What is the measure of an exterior angle of a regular decagon?
36 degrees.Exterior angles always add up to 360. So 360 divided by 10 is 36. Which means 36 is the measure of one exterior angle.360/10 = 36 degrees
What is the measure of one angle of a regular decagon?
144
What is the measure of one exterior angle of a regular decagon?
36oFor all polygons, the sum of the exterior angles is 360o.For a regular polygon they are all the same thus:exterior_angle = 360o ÷ number_of_sidesSo for a decagon with 10 sides this becomes:exterior_angle = 360o ÷ 10= 36oIt is 36 degrees
A regular decagon is inscribed in a circle find the measure of each minor arc?
The measure of an exterior angle of an equiangular pentagon is 72 degrees. An equiangular pentagon is a regular pentagon that has five equal sides and five equal angles. An interior angle of a pentagon is equal to 108 degrees.
How many degrees does one angle in a decagon measure?
Interior angle: 144 degrees
What is the sum of a polygon's interior angle measure if one exterior angle of a regular polygon measures thirty-six degrees?
Number of sides = 360/ exterior angle = 360/36 = 10 decagon interior angles total (20 - 4) x 90 ie 1440o
What is the exterior angle of a hexagon?
what are the exterior Angles of a hexagon, heptagon, octagon, decagon and an icosagon ?If all the exterior angles of a hexagon or any polygon equal 360, then just divide by the number of vertices and there's one exterior angle of the polygon.
How many sides does a regular polygon have if one interior angle is 144?
It is a decagon (10 sides) because if the interior angle is 144° then the exterior is 36°. 360 Divided by 36 is 10 and so it is a decagon.
If one exterior angle of a polygon measures 36 degrees what is the sum of the polygons exterior angles?
The sum of the exterior angles in any polygon is 360 degrees.Therefore that polygon is a decagon.
What is the measure of one interior angle of a regular decagon?
Each interior angle measures 144 degrees
What would the measure of one exterior angle of a regular hexagon?
360/6 = an exterior angle of 60 degrees
What is the measures of one exterior angle of a regular 18-gon?
The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be: 360° 18 = 20°Therefore the measure of one exterior angle of a regular 18-gon is 20°.
