Question 886533
Two ships are sailing a direct course into harbor.
 Ship A is 22 miles from harbor. Ship B is sailing into harbor on a course perpendicular to that of ship A.
 If the angle between them is 47 degrees, how far is ship B from the harbor? Round the answer to the nearest tenth.
:
let b = B's dist from port
this is right triangle problem, we can use the tangent of 47 degrees, where
side opposite = 22 degrees and b = side adjacent
Solve this
tan(47) = {{{22/b}}}
