Question

A circle is divided into 20 equal parts. What is the angle measure of three of those left parts?

Answer 1

54

Explanation:

A circle is 360 degrees

We divide it into 20 parts

360/20 = 18

Each part is 18 degrees

We want the angle means of 3 of the parts

3*18 = 54

Three of the parts measures 54 degrees
