Step-by-step explanation:
Let alpha be the unknown angle. We can set up our sine law as follows:

or

Solving for alpha,

Answer:
36 bottles
Step-by-step explanation:
Each spherical bottle will have a volume of ...
V = (4/3)πr³ = (4/3)π(4.57³) = 399.8 . . . . cubic inches
Each box (12-pack?) will have a volume of ...
V = LWH = (15 in)(5 in)(4.4 in) = 330 in³
This is a smaller volume than even one spherical bottle, so 36 bottles will have the larger volume.
Answer:
We add 25 and subtract 25 to complete the square.
is the equation we get.
Step-by-step explanation:

So, we're adding 25-25 to complete the square.
