Answer: 66.4

Step-by-step explanation:

The trig ratio you would use is inverse cosine or [tex]cos^{-1}[/tex].

Cos is adjacent/hypotenuse

So, the ratio you would use is  [tex]cos^{-1}[/tex] [tex]\frac{2}{5}[/tex].

Insert this in a calculator which come out to be 66.421821522.

But you have to round, so you answer is 66.4.
