Question

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.

Answer 1

tan49=h/900

Answer 2

therefore h=900tan49 = 1035.33

Answer 3

Thanks yet again @CrashOnce lol. So you basically multiplied 900ft by the tangent of 49º?

Answer 4

ya

Answer 5

tan49=h/900
therefore h=900tan49 = 1035.33
