The bearing of a road between two
points, A and B, is the measure of
the positive angle with vertex at
point A that is measured clockwise
to point B. Find the bearing of a
road that runs directly from A to B if
B is 3 miles north and 1.7 miles east
of point A. (Draw a picture, with a right
triangle, find "A, round to the nearest
degree.)
