Answer:
The height of the building is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC

we have

substitute and solve for BC


Find the height of the building
The height of the building (h) is equal to

First of all, let's convert all the measures to the same unit: 4 feet are 48 inches.
Now, as the wheel turns, there is a proportion between the angle and the distance travelled: for example, when the car moves forward a whole circumference, the angle will be 360°. Conversely, if the wheel turns 180°, then the car will move forward a distance which is half the circumference of the wheel, and so on.
Since the radius is 16 inches, the circumference will be

So, we have the following proportion:

that you can read as: "if an angle of 360 corresponds to a distance travelled of
, then the unknown angle x corresponds to a distance travelled of 48 inches.
Solving for x, we have

Rewrite in standard form using (h,k) to find the vertex.
(3,4) is the answer.
