Correct Answer

A

Explanation

To find the number of sides of a regular polygon given the measure of each interior angle, we can use the formula:Interior angle = (n - 2) * 180 / nwhere n is the number of sides of the polygon.In this case, we have an interior angle of 140 degrees.140 = (n - 2) * 180 / nTo solve for n, we can cross-multiply and simplify the equation:140n = 180n - 360360 = 180n - 140n360 = 40nn = 360 / 40n = 9Therefore, the polygon has 9 sides.
