A marine surveyor uses a rangefinder and a compass to locate a ship and an island in the vicinity of the coast on which she stands. The rangefinder indicates that the island is 353 ft from her position and the ship is 474 ft from her position. Using the compass, she finds that the ship's azimuth (the direction measured as an angle from north) is 320 degrees and that of the island is 58 degrees. What is the distance between the ship and the island?

distance between the ship and the island is 465.72 ft
Step-by-step explanation:
given data
island = 353 ft
ship = 474 ft
ship's azimuth = 320 degrees
island = 58 degrees
to find out
distance between the ship and the island
solution
as per given figure we can see that
AC = 353
AB = 474
we get here angle ABC that is = 360 - 320 = 40 degree
and angle BAC is = 180 - 58 = 122
and now we apply here law sign
so
put here value and we get
BC = 465.72 ft
so distance between the ship and the island is 465.72 ft
