Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°
99 plus 9 tens?? if so, 189
Breads/cereals;
11 * 140 = 1540 calories
Fruits/vegetables;
9 * 60 = 540 calories
Meat/milk;
x * 180 = 2800 - (1540 + 540)
180x = 2800 - 2080
180x = 720
x = 4 servings
R= 18
d=r(2)
36=r(2)
36/2=r(2)/2
18=r
