Answer:

about 0.31°

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°.
