Question

A passenger on a cruise ship is positioned 42m above the water level and is admiring a tropical island in the distance. One end of the island is at a true bearing of 028 degrees and has an angle of depression of 11 degrees. While the other end is at a true bearing of 118 degrees and has an angle of depression of 19 degrees. How long is the island to the nearest metre?

Please draw a diagram and explain.

Answer 1

Distance to end A
use the same example to find the distance to end B
