A boat leaves the entrance to a harbor and travels 150 miles on a bearing of N 59° E. How many miles north and how many miles ea st from the harbor has the boat traveled?
2 answers:
N 59° E = 90-59 = 31° Distance N = 150 sin (31°) = 77.25 Distance E = 150 cos(31°) = 128.58
X=miles north
cos53=x/150
x=90.3 miles north
y=miles East
sin53=y/150
y=119.8 miles East
