    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.
