dollars
=> 2.1 x 20 = 21 there are a total of 21 ounce of bar
=> 21 / 15.37
=> 1.366 dollars / ounce
12 pack of 1.4 ounce bars = costs 15.35
=> 1.4 x 12 = 16.8, there are 1a total of 6.8 ounces of bar

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
It's irrational, √11<span>≈3.3
