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

please help

Answer 2

its my last question and i am stuck

Answer 3

somebody please

Answer 4

You can set up the following equation:
\[\tan49^\circ=\frac{x}{900}\]
and solve for \(x\).

Answer 5

Then again, the question asks for the height of the helicopter above the building, not above the ground... Any idea how tall the building is? Or is the observer standing at a height equivalent to the building's height?
