h = 221.7 m

Step-by-step explanation:

It is given that,

An observer (O) is located 400 feet from a building (B). The observer notices a kite (K) flying at a 29° angle of elevation from his line of sight. We need to find how high is the kite flying over the building?

The attached figure shows the whole scenario. It means we need to find the value of h.

Using trigonometry as follows :

So, the bird is flying at a height of 221.7 m over the building.
