Final Jeopardy
ANSWER:
• 2591.20 ft
In order to calculate the height of a mountain peak, a surveyor measured the angle of elevation from a certain stake and found it to be . Then he advances over a ground level toward the peak and set a second stake, from which the angle of elevation was found to be . The distance between the stakes was ft. Find the height of the peak above ground level.
