Question

a boat travels on a course of bearing n 37 10' W for 79.5 miles. How many miles north and how many miles west has the boat traveled?

Answer 1

d = 79.5mi[N37o 10'W] = 79.5mi[127.17o]
CCW.

X = 79.5*Cos127.17 = Miles west.
Y = 79.5*sin127.17 = Miles north.

Answer 2

Those answers are wrong

Answer 3

79.5cos37.17 = 63.4 miles north
79.5sin37.17 = 48.0 miles west
