    You have 18 sides because of:

    (x - 2) * 180 = 160x

    180x - 360 = 160x

    20x = 360

    x = 18

    A polygon has five sides . So 160 x 5 = 800

    measure of internal angle of a polygon with "n" sides = (n-2)*180/n degrees

    (n-2)*180/n = 160

    (n-2)*180 = 160n

    180n - 360 = 160n

    20n = 360

    n = 18 sides
