Question

A circle is divided into 9 equal parts. What is the angle measure of two of those parts?

Answer 1

There are 360 degrees in a circle. That means that we first divide 360 by 9.
360/9=40
We have the measure for one of the nine parts of the circle, but we need two. All we do is multiply 40 by 2 to get 80 degrees.

Answer 2

80 degrees cause you divide 360 by 9 which equals 40 and multiply that by 2
