if the difference in the degree measure of an interior and exterior angle of a regular polygon is 100 degree,how many sides doesthe poygon have??

To find the number of sides of a regular polygon given the difference in the degree measure of an interior and exterior angle, we can use the following formula:

n = 360 / (exterior angle - interior angle)

In this case, the given difference is 100 degrees. So, we can substitute the values into the formula:

n = 360 / (exterior angle - interior angle)
n = 360 / (x - (x + 100))
n = 360 / (-100)

Since the denominator is -100, we can flip the sign and divide:

n = 360 / 100
n = 3.6

However, since a polygon cannot have a fractional number of sides, we round the answer to the nearest whole number.

n ≈ 4

Therefore, the polygon has 4 sides.
