  1. Answer:

    C.  20

    Step-by-step explanation:

    given:

    exterior angle = 18°

    to find the number of sides of a polygon:

    the formula would be:

    360 =  exterior angle

     n

    360 =  18

     n

    n = 360/18

    n = 20

    therefore, the number of sides of a polygon is 20
