The measures of the angles in a hexagon are in ratio 4:5:5:8:9:9. Find the measure of the smallest angle.
Your answer is 72. Add all the numbers. That is 40. Find the total number of degrees a hexagon contains. 720 degrees in all. 720/40 = 18. Since the smallest angle is 4 in the ratio, multiply 18 by 4. That gives you 72.
