Answer:
18°
Step-by-step explanation:
The law of cosines tells you ...
a² = b² + c² -2bc·cos(A)
Solve for cos(A) and fill in the numbers. Note that the value of cos(A) is very close to 1, so the angle will be fairly small. This by itself can steer you to the correct answer.
cos(A) = (b² +c² -a²)/(2bc) = (49 +100 -16)/(2·7·10) = 133/140
A = arccos(133/140) ≈ 18.2° ≈ 18°

Step-by-step explanation:
From my understanding, all numbers 300 and below represent defective mp3s, so there's two.
If a recipe calls for 5/8 cup of milk for a cake. How much milk is in 1 2/7 cake
There are two eggs per cup of milk in this recipe.
In a cake recipe, there are 4 eggs and 2 cups of milk, thus there are 4 eggs and 2 cups of milk in total.
Now, the ratio of eggs to milk in this recipe is:
Totalnumberof eggs /
totalnumberof cups of milk
= 4/2
= Number of eggs = 2
Consequently, there are two eggs per cup of milk in this recipe.
