The shipmate must travel 54.48 miles to the south

Step-by-step explanation:

We need to know how many miles south the shipmate traveled. So, we need to find the opposite side of the 27 ° angle shown in the triangle of the attached image.

To find this distance we use the following identity:

$sin(\theta) = \frac{lado\ opuesto}{hipotenusa}$

We know that the angle $\theta$ = 27 °.

So:

$sin(27\°) = \frac{x}{120}\\\\x = 120sin(27)\\\\x = 54.48\ millas$

The shipmate must travel 54.48 miles to the south
