From the top of a 400 feet tower, an elephant observed the zoo keeper. The angle of depression from the elephant to the zoo keeper changes from 17 degrees to 34 degrees.

a. How far does the zoo keeper travel if the angle of depression from the elephant on the top of the tower to the zoo keeper changes from 17 degrees to 34 degrees?

b. There is a store right next to the Tower, the angle of elevation from the top of te store to the tower is 46 degree, how tall is the store?

c. What is the angle of elevation from the store to the man if the store is 360 feet away from the zoo keeper?

A Giraffe is traveling threw a forest and encounters a 53 ft. tall house. From the top of his head to the top of the house changed from 10 degrees to 80 degrees as the Giraffe walks. The Giraffe makes a Horizontal distance from the top of his head to a window in the house.When the giraffe stops walking he spots a balloon floating above the house his angle of elevation changes from 10 degrees to 20 degrees.

- How far did the Giraffe travel as he was walking away from the House and his angle of elevation changed from 10 degrees to 80 degrees?
- How high is the window from the ground?
- How tall is the Giraffe?
- How high up is the balloon from the ground when your angle of elevation changed from 10 degrees to 20 degrees?
