Question
A small plane takes off from island A and flies in a straight line for 12 kilometers. At the same time, a sailor sitting in a sailboat who is 5 miles from the island measures the angled by from island A to the sailboat and the plane is 37 degrees. How far is the plane from island B? Please draw and label the situation if possible.
Answers
The wording is quite muddled in the middle of your post.
However, I think we have a cosine law problem here, with sides 12 and 5 and the contained angle as 37 degrees
d = 12^2 + 5^2 - 2(12)(5)cos37
= ....
