A 2.05m man, standing in front of a street light 3.08m high, casts a 1.5m shadow. What is the angle of elevation from the ground to the source of light?

Answer 1

review your basic trig functions, and you will note that

tanθ = 2.05/1.5

The height of the light does not really matter. It will just help to determine how far away from the lamp the man is standing.

Answer 2
