Question

The sum of the interior angle measures in a regular polygon is 1260∘ . What is the measure of one of the interior angles of the polygon?

Answer 1

Answer:

140 degree

Step-by-step explanation:

The sum of the interior angle measures in a regular polygon is 1260 degree.

(n-2)*180=1260

180n-360=1260

180n=1260+360

180n=1620

n=1620/180

n=9

Now, evaluate the measure of one of the interior angles of the polygon.

((9-2)*180)/9=140 degree.

Answer 2

Answer:

140 degrees is the answer
