follow the method I showed you in the two previous posts.
you could also make a sketch and solve it using basic trig
I see a triangle with sides 100 and 60 and the contained angle of 160°
by the cosine law
x^2 = 100^2+60^2-2(100)(60)cos120
....
In an orienteering race, you walk 100 m due east and then walk N70¡ÆE for 60 m. How far are you from your
starting position, and at what bearing?
