Question

Meekah is looking at a bird perched on top of a streetlight. Her line of sight, which is the diagonal distance to the top of the streetlight, is 16 feet, and she is standing 6 feet from the base of the streetlight. Use the inverse of cosine to find the angle of elevation with which she is looking at the bird. Round your answer to the nearest whole degree. _degrees.

Answer 1

cos θ = adjacent/hypotenuse = 6/16 = 3/8, so θ = cos⁻¹(3/8) ≈ 67.98°.
Rounded to the nearest degree, θ ≈ 68°.
