two ships p and q left a
port at the same time. q sailed on a
bearing of 150 while p sailed on the
north side of q. after a distance of
8km and 10km by pand q
respectively, their distance apart
was 12km. find the bearing of p
and r

1. Steve

who is r?

If x is the angle between p and q, then

12^2 = 8^2+10^2-160cos(x)

Now subtract x from q's heading (not bearing!)
