Best ResponseYou've already chosen the best response.1After you draw your picture, you see that you are talking about a triangle with a 60 degree angle. The sides that form the 60 degree angle are 3(12) and 3(16) or 36 and 48. So now you can use the law of cosines using the 60 degree angle as C and the required distance as c. So: c^2 = 48^2+36^2  2(48)(36)cos 60 c^2 = 2304+12963456(.5) c^2 = 36001728 c^2 = 1872 c = 43.3 miles
