Answer:
A. 17
Step-by-step explanation:
using the cosine rule (also see attached for reference):
AB² = BC² + AC² - 2·AC·BC cos C
2·AC·BC cos C = BC² + AC² - AB²
Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula
2(18)(28) cos C = 28² + 18² - 12²
1008 cos C = 964
cos C = 964/1008
cos C = 0.9563
C = cos⁻¹ 0.9563
C = 16.99 ( = 17° rounded to nearest degree)
The best and most correct answer among the choices provided by your question is the second choice or letter B.

Answer:
We need to make a conversion for the new recipe. If the regular recipe calls for 2 cups of Sugar, we can make a conversion for the new recipe.
Step-by-step explanation:
Conversion- 2:7= 1:4 (sugar)
2:7 (sugar)
3: x (flour)
1: y (milk)
X= 8 (flour)
Y= 6 (milk)
NEW RECIPE:
3.5 cups of milk
10.5 cups of flour
7 cups Sugar
We found this by seeing the new recipe adds 5 more cups with the original amount :)
