Answer:
12.449899598
Step-by-step explanation:
You would use pythagoras thereom.
C^2=A^2+B^2
The hypotenuse is C (which is the longest side of the triangle - 18).
18×18=13×13+B^2
324=169+B^2
324-169=B^2
155=B^2
Square root B to get B on it's own which would be 12.449899598.

Hello!
To find how far the ship has sailed, we need to use the distance formula. The distance formula is:
.
Before using the formula, we need to assign the given points to
and
. The point (1, 2) can be assigned to
and (5, 5) can be assigned to
.
With the assigned ordered pairs, we can substitute it into the formula.




Given that each unit represents one mile, then therefore the ship has sailed 5 miles, which is choice A.
