Chapter 8.1, Problem 5MP

Repeat Example 5 assuming that the man is standing 75 feet from the wall.

Advertising An advertising agency is designing a billboard that is 40 feet long and 12 feet high. The billboard is mounted on a wall so that the bottom of the billboard is 30 feet above the ground. Suppose that a man, whose eyes are 6 feet above the ground, stands 150 feet from the wall. Find the angle θ (to the nearest degree) between the man’s line of sight to the top of the billboard and his line of sight to the bottom of the billboard (see Fig. 17).
