Answer 1

9514 1404 393

Answer:

  about 0.31°

Step-by-step explanation:

First of all, solve for sin(2θ):

  3000 = (1/32)(3000^2)sin(2θ)

  32(3000)/3000^2 = sin(2θ)

  4/375 = sin(2θ) . . . . . . . simplify

Now, we find the corresponding angle:

  2θ = arcsin(4/375) ≈ 0.61117°

  θ ≈ 0.30558° ≈ 0.31°

The angle of elevation must be about 0.31°.
