The distance between port 3 to port 1 is 7.7 miles.
Distance is the length along a line or line segment between two points on the line or line segment.
Here, a rough sketch is attached.
The angle between 3.5 and 6 is = (90⁰ + 15⁰) = 105⁰.
We will need the law of cosine = [tex]\sqrt{a^2 + b^2 -2abcos\alpha }[/tex]
So the distance between port 3 to port 1 is:
[tex]\sqrt{3.5^2 + 6^2 -2 X 3.5 X 6 X cos 105 }[/tex]
= 7.6889
≈ 7.7
Thus, the distance between port 3 to port 1 is 7.7 miles.
