. A drone is hovering above a tree. You are standing 40 feet from the base of the tree. The angle
of elevation to the top of the tree (from the ground) is 33°, and the angle of elevation to the
drone is 44°. What is the distance between the drone and the top of the tree?
2. Paul stands on the roof of a building that he knows is about 1100 ft. tall. He wants to estimate
the height of a neighboring building. He measures the angles of depression to the top of the
neighboring building and to the bottom of the neighboring building. He finds these angles to be
28° and 65°, respectively. How tall is the neighboring building?
3. Ruby wants to estimate the height of a streetlamp post on her block. She stands a certain
distance from streetlamp post and measures the angle of elevation to the top of the post (from
the ground) to be 71°. She walks 12 feet away from the lamp post. She then measures the angle
of elevation to the top of the post again, and this time finds it to be 46°. Estimate the height
