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

The equation of a circle is used to calculate the radius and the center of the circle.
The equation of the circle is:
The given parameters are:
--- center
Tangent to both axes
The equation of a circle is:
where (h, k) is the center and
r is the radius.
If a circle is tangent to both axes, then
Where h and k have different signs
i.e.
This means that:
Divide both sides by 2
Recall that:
This means:
Recall that:
This means that:
Recall that:
Substitute values for h, k and r
Hence, the equation of the circle is:
