Question

Meekah is looking at a bird perched on top of a street light. Her line of sight, which is the diagonaldistance to the top of the street light is 16 feet and she is standing 8 feet from the base. Find the angleof elevation with which she is looking at the bird. Round your answer to the nearest whole degree.

The angle of elevation is
degrees

Answer 1

We have cos θ = adjacent/hypotenuse = 8/16 = 1/2, so θ = arccos(1/2) = 60°.

The angle of elevation is 60 degrees.
