The Attempt at a Solution
I have drawn out the photo and it has a base of 15 miles and degree angles of 31, 53 and 96
I assumed the fastest route was a straight line back and that would cut the triangle into 2 different right triangles with their bases added together = 15 miles. I am confused if I should do a system of linear equations to make the straight line back to the shore being the unknown but then we have even more unknowns so I have no idea what to do. Any guidance for me please :( Iv'e got the Exam tomorrow and this is the last part of the chapter and most of it is still unknown for me.
