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. How high is the kite flying over the building? You must show all work and calculations to receive full credit. A right triangle is shown with one leg measuring 400 and another leg measuring h, with an angle across from it measuring 29 degrees.

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.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
