How many Sides does a polygon have with 140 degree angles?
The sum of the angles : (n - 2)180° The measure of one angle: [(n - 2)180°]/n Then we have: [(n - 2)180°]/n = 140° multiply by n to both sides; [(n - 2)180°] = 140°n 180°n - 360° = 140°n divide by 20 to both sides; 9°n - 18° = 7°n subtract 7°n and add 18° to both sides; 2°n = 18° divide by 2° to both sides; n = 9 Thus, the regular polygon has 9 sides.
Each interior angle of a regular n-gon has a measure of 140 degrees. find n?
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
What is the answer of 140 divided by N equal 120?

2 plus n is the true one, but 1 plus n is not?
