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?



Answer :

A circle has 360 degrees.  If it was divided into 18 equal parts, simply divide 360 by 18 to find the degrees of each angle.
360/18= 20 degrees.

Do the same when dividing a circle into 5 parts:
360/5= 72 degrees.

The angle for each part is 20° and for 5 parts, the angle will measure 100°.

As we know for a circle the full measure of angle is 360°.

Therefore, if we divide it in 18 parts,

each part will measure = [tex]\dfrac{360}{18}[/tex] = 20°,

For 5 parts, the angle will measure = 20° x 5 = 100°,

Hence, the angle for each part is 20° and for 5 parts, the angle will measure 100°.
