1190.35 ft
Step-by-step explanation:
The figure for the given scenario is shown below.
From the triangle Δ ABC, AB is the height of mountain, BC is the distance of campsite from the foot of mountain and is the depression angle.
So, °
Let the side BC be ft.
Now, the tan of the angle A is given as:
Plug in for BC, 1700 ft for AB and 35° for . Solve for . This gives,
Therefore, the distance of campsite from the foot of the mountain is 1190.35 ft.
