The second sails at 34 mph in a direction 220, Assuming that both boats maintain speed and heading, after 3 hours, how far apart are the boats A) 137.2 miles B) 141.9 miles C) 103.9 miles D) 87.6 milesExplanation / Answer
BC = 1369 m
B = 106.2
C = 17.1
A = 180 - ( 106.2 + 17.1 )
A = 56.7
applying law of sines
1369/ sin 56.7 = AB / sin 17.1
AB = 481.62
AB = 482 metres
option b is correct
