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. What equation and trigonometric function can be used to solve for the height (h) of the helicopter? What is the height of the helicopter? Pick another trigonometric function and describe why that function is not appropriate when trying to solve for (h). You must show all work and calculations to receive full credit.

Best ResponseYou've already chosen the best response.2Since the tangent of the angle= opposite over the adjacent, we can say that from the diagram tan(49)=h900 That makes the height=900 tan(49) which you can find using a calculator
