a circle is divided into 18 equal parts. how many degrees is the angle for each part? how many degrees is the angle for 5 parts?
A circle has 360 degree for angle. Thus when divided by 18, each part has 360/18= 20 degree for angle. When divided into 5 parts, each part has 360/5 = 72 degree.
Divide 360 by 18.
Divide 360 by 5.
