Step-by-step explanation:

It is (D) I believe. From what I can see it is going down from 1.40 to 1.39 from November to December which is a loss of 0.01
Using Sine.
Sine = Opposite / Hypotenuse
sin 60° = a / (6√3) But sin60° = √3/2
√3/2 = a/(6√3)
Cross multiply
2*a = 6√3 * √3
2a = 6 * √(3*3)
2a = 6*3
a = 6*3/2
a = 3*3 = 9
Option E.
