Let the position of the submarine be represented with X
Given



First, we calculate angle at X.




Solving (a): Distance AX: The distance between ship A and the submarine
To do this, we apply sine formula which states

In this case:

Substitute values for AB,
and 

Make AX the subject





Solving (b): Distance BX: The distance between ship B and the submarine
To do this, we apply sine formula which states
In this case:

Substitute values for AB,
and 

Make BX the subject





X + (x + 2) + (x + 4) + (x + 6) = 156
x + x + x + x + 2 + 4 + 6 = 156
4x + 12 = 156
- 12 - 12
4x = 144
4 4
x = 36
x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42
Add them all up and divide by 5
