Lewis is hiking in a state park when he spots a brightly colored bird in a distant tree. Lewis is 60 feet away from the tree, and the bird is perched on a branch 22 feet above the ground. Lewis is 5 feet tall.

What is the angle of elevation, in degrees, of Lewis' line of sight to the bird?

Quite certain it'd be 15.8 degrees.

Think about it, we're trying to figure out his angle of sight. If his eyes are 5 feet above ground, and the bird is 22 feet off the ground, there's really only a 17 ft height difference between the two. After doing the formulas and all, we can see that the angle of his vision is approximately 15.8.
