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.
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.
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.
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).
Each exterior angle: 40 degrees Each interior angle: 140 degrees
Answer: n=9---- Explanation:140 degrees is the measure of each angle and the sum of the interior angle is180(n-2)So we have 140(n) is the sum of the n interior angles.140n=180(n-2)140n=180n-360-40n=-360n=9Check it:180(9-2)=1260 divide this by 9 and we have 140 as desired
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.
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.
If it's a regular 9 sided polygon then each interior angle will measure 140 degrees.
Each interior angle of a regular nonagon measures 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
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.
140 degrees
Each interior angle measures 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.
18
140 degrees
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.
