Question

Trig question: UPDATED.
(basically a ship sunk and it has gold, and this guy who wants the gold wants to avoid Blackbeard so he's gonna send out a decoy ship. Blackbeard captures "you" to figure out which ship is really going after the gold)

I got the same results for both ships so I can't figure out which one is the real one :\

Answer 8

then for the last part, you can use pythagoras... but I got 51.07... which makes sense as the triangle formed by the shore, boat and diver is almost isosceles...

Doesn't 80° to the north mean 180°-80° =100° oo.?
