A circle is divided into 8 equal parts. What is the total angle measure of 4 parts
Since the circle is divided into 8 equal parts, each part will have an angle measure of 360/8 = 45 degrees.
To find the total angle measure of 4 parts, we need to multiply the angle measure of each part by the number of parts we are interested in.
Total angle measure of 4 parts = (angle measure of each part) x (number of parts) = 45 degrees x 4 = 180 degrees.
Therefore, the total angle measure of 4 parts is 180 degrees.
