Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
Answer:
1
Step-by-step explanation:
9 + 1 is equal to 10. Therefore, the answer is 1.

1) 10.5 = 10 1/2 = 21/2 ounces in bottle
2) 21/2 * 1/16 = 21/32 ounces one use
3) 21/32 * 6 = 63/16 ounces six use
4) 21/2 - 63/16 = 168/16 - 63/16 = 105/16 = 6 9/16 ounces left
