Step-by-step explanation:

An observer (O) is located 500 feet from a school (S).

The angle of elevation from his line of sight is 39°.

We need to find how high is the bird flying over  the school. Let BS = h. We can find it using trigonometry as follows :

P is perpendicular and B is base

P = BS = h, B = 500 feet and

So,

So, the bird is at a height of 404.89 feet,
