An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation from his line of sight. How high is the helicopter flying over the building? You must show all work and calculations to receive full credit.

h = 1035.33

Step-by-step explanation:

You can use tangent to help you solve this problem. Remember tan is opposite over adjacent.

Step 1: Write out equation w/ known variables

tan(49°) = h / 900

Step 2: Solve

900tan(49°) = h

Plug it into your calc and you should get h = 1035.33 ft

And you have your final answer!

h = 1035.33
