  1. You want to install a ramp from the stage to the pit in the cafeteria. If the stage is 4 feet off of the ground and the angle of depression must be 20, how long must the ramp be in order to reach the ground?

4. Refer to the diagram. Round all answers to the nearest tenth.

5. You are at a parade looking up at a balloon floating directly above the street. You are 60 feet from

a point on the street directly beneath the balloon. To see the top of the balloon, you look up at an

angle of 53°. To see the bottom of the balloon, you look up at an angle of 29°. Estimate the height h

of the balloon to the nearest foot.
