As shown below, 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? You must show all work and calculations to receive full credit.

A right triangle is shown with one leg measuring 900 and another leg measuring h. One angle is marked 49 degrees.
