A circle is divided into 9 equals parts. A circle is a round, therefore it has 360°. To solve the problem we have to use division.  

360° ÷ 9 = 40 

40° is the angle measure of two of those parts.

A whole circle is 360 degrees so 360 divided by 9 equals 40 so each part is 40 degrees so 40+40=80. Your answer is 80
