Answer:
The ships are 66 meters apart.
Step-by-step explanation:
For the sake of convenience, let us label ships A and B
As shown in the figure, the distances to the ships from right triangles.
The distance to the ship A is 
and it is given by
And the distance to the ship B is 
and is given by
Therefore, the distance 
between the ships A and B is
In other words, the ships are 66 meters apart.
