12. A pilot wishes to fly from Toronto to Montreal, a distance
of 508 km on a bearing of 075^o. The cruising speed of the plane
is 550 km/h. An 80 km/h wind is blowing on a bearing of 125^o a)
What heading should the pilot take to reach his destination? b)
What will be the speed of the plane relative to the ground? c)
How long will the trip take? I do not know how to get the angle
the pilot should take. I don't understand how to do it. I know
there is a little angle of 15^o, however, can't find the angle
in the triangle to add to the little angle then subtract it from
90^o. I know this is easy, however, can't seem find the method
to find the bearing. NOTE: All angles are from true North [up]
and then rotate clockwise.
