If the measure of an exterior angle of a regular polygon is 20 degrees, how many sides does the polygon have?

the regular polygon would have 18 sides. because you do 180 deg-20deg=160 deg. then multiply 160 and 18 to get to2880. each exterior angle of a polygon is 20 degress. so the polygon has 360/20=18 sides. (i think)

i think asking google will you get the answer to that question
