What is the number of sides of a polygon if each of its exterior angles measure 140?

The exterior angle would have to be greater than 180 degrees. If you mean interior angle then a regular nonagon (9 sided) will have angles of 140 degrees.

Number of exterior angles of polygon?
The exterior angles of any polygon are as many as their sides.
How many sides does a regular polygon have if the measure of an exterior angle is 45?
Sum of exterior angles = 360 degrees. Number of exterior angles = 360/45 = 8 So the polygon has 8 angles and so 8 sides.
Find the measure of each exterior angle of a regular polygon?
Exterior angles of ANY polygon add to 360 degrees. Individual angles are therefore 360/n where n is the number if sides. 72
How many sides does a regular polygon have if each exterior angle measure is 30?
12 The sum of the exterior angles is 360˚. So we have 360/30 = 12 angles which is also the number of the polygon sides.
What happens to the exterior angles on a polygon as the number of sides increase?
The exterior angles get smaller
What is the measure ofr a regular polygon with an exterior angle of 18.95?
There can be no such polygon. The sum of the exterior angles of ANY polygon is 360 degrees. If it is a regular polygon, then the number of angles MUST divide 360 degrees. Since 18.95 does not divide 360, there cannot be such a polygon. If the exterior angle was 18.94737... degrees, it would be a 19-sided polygon.
What is the sum of the measures of the exterior angles of a polygon?
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
How many sides does a polygon have if the measure of each exterior angle of a regular polygon is 45 degrees?
8 Since the sum of the exterior angles of any polygon is always 360, you can divide 360 by 45 to find the number of exterior angles, which is 8. That means 8 interior angles and eight sides as well.
How is the number is the number of sides related to the sum of exterior angles in a polygon?
It is not.The sum of the exterior angles of EVERY polygon is 360 degrees, so the number of sides has no role.
What is the sum of the measure of the interior angles of a regular polygon if each exterior angle measures 120 degrees?
number of sides = 360/exterior angle = 360/120 = 3 polygon is therefore a triangle, interior angles total 180o
What is the number of sides of a regular polygon if one of its exterior angles measure 45 degrees?
It is a regular octagon which has 8 sides
How do you find the number of sides a regular poly gon has by knowing the angles?
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
