The definition of the tangent function tells you
tan(angle) = (300 ft) / (distance to mountain)
This equation can be rearranged to
(distance to mountain) = (300 ft) / tan(angle)
For the far end of the river,
distance to far end = (300 ft) / tan(24°) ≈ 673.8 ft
For the near end of the river
distance to near end = (300 ft) / tan(40°) ≈ 357.5 ft
Then the width of the river can be calculated by finding the difference of these distances:
width of river = distance to far end - distance to near end
width of river = 673.8 ft - 357.5 ft
width of river = 316.3 ft
The appropriate answer choice is
316 ft.
The Trump tower is 316 feet taller than the Chrysler building.
Answer:

Step-by-step explanation:
Please see attached picture for full solution.
1. Label the hypotenuse, adjacent and opposite side of the triangle.
2. Look at the given information.
3. Decide if you should use sine, cosine or tangent.
sine angle= opp/hyp
cosine angle= adj/hyp
tangent angle= opp/adj
