Question

Ahmed is sitting on a dock watching a float plane in a harbour. At a certain time, the plane is 350 m above the water and 470 m from Ahmed. Determine the angle of elevation of the plane
measured from Ahmed, to the nearest degree.

Answer 1

9514 1404 393

Answer:

  48°

Step-by-step explanation:

The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(α) = (350 m)/(470 m) = 35/47

  α = arcsin(35/47) ≈ 48.13°

The angle of elevation of the plane is about 48°.
