Distance and Bearing Problems 27 through 32 involve directions in the form of bearing, which we defined in this section. Remember that bearing is always measured from a north-south line. A man wandering in the desert walks 2.3 miles in the direction S 310 W. He then turns 90 and walks 3.5 miles in the direction N 59 W. At that time, how far is he from his starting point, and what is his bearing from his starting point?

Height of a Tree An ecologist wishes to find the height of a redwood tree that is on the other side of a creek, as shown in Figure 19. From point A he finds that the angle of elevation to the top of the tree is 10.7. He then walks 24.8 feet at a right angle from point A to point B. There he finds that the angle between AB and a line extending from B to the tree is 86.6. What is the height of the tree? Figure 19
