It could be an obtuse triangle.
If it were a regular polygon then each of its external angles would be 180 -140 = 40 degrees.
The sum of the external angles of any polygon is 360 degrees.
So if each is 40 degrees, there must be 360/40 = 9 of them.
So the polygon is a nonagon, BUT ONLY IF IT IS A REGULAR POLYGON.

What is the number of sides of a regular polygon if one angle measures 140 degrees?
Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.
What is the interior angle of a 9 sided polygon?
140
Each interior angle of a regular polygon is 140 How many sides has the polygon?
Interior angle = 140 deg so exterior angle = 40 deg. Sum of exterior angles = 360 so 360/40 = 9 such angles required. So the figure has 9 sides.
How many sides does a regular polygon have with one interior angle measuring 140 degrees?
If the interior angle = 140 degrees, then the exterior angle = 180 degrees - 140 degrees = 40 degrees. So the number of sides is 360 degrees / 40 degrees = 9 sides (a nonagon).
What is the measure of each interior and each exterior angle of a regular nonagon?
Each exterior angle: 40 degrees Each interior angle: 140 degrees
If the measure of an interior angle of a regular polygon is 140 how many sides does the polygon have?
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
What is the number of sides of a regular polygon if one angle measures 140 degrees?
Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.
What is the measure of a one angle of an 9gon?
If it's a regular 9 sided polygon then each interior angle will measure 140 degrees.
What is the measure of one interior angle of a regular polygon with nine sides?
Each interior angle of a regular nonagon measures 140 degrees.
What is the measure of each interior angle in a regular polygon that is 140 degrees?
The minimum interior angles of a polygon add up to 180 degrees which would give each interior angle of an equilateral triangle 60 degrees
What is the interior angle of a 9 sided polygon?
140
If the measure of one interior angle of a regular polygon is 140 degrees how many sides does the polygon have?
Since interior angle+exterior angle=180 degrees We can find out the exterior angle by doing 180-140=40 degrees. To find out the number of sides we simply do 360/40=9 So the polygon has 9 sides.
Interior angle of 9 sided polygon?
140 degrees
What is the interior angle of a regular 9 sided polygon?
Each interior angle measures 140 degrees
How many sides does a regular polygon have if each interior angle has a measure of 140 degrees?
If each interior angle is 140, each exterior angle is 180 - 140 = 40. Exterior angles add up to 360, so the number of sides is 360 / ext angle = 360 / 40 = 9.
What is the measure of an interior angle on a nonogon?
140 degrees
What is the number of sides of a regular polygon where each interior angle is 140 degree greater than each interior angle?
18
