Answer:

0.0349207695 mi

Step-by-step explanation:

Well, I guess you start with a triangle.

Let O be the point 1 mile from the building.

Let B be the bottom of the building

Let H be the top of the building.

Angle HOB is given (2 degrees)

Side OB is given as 1 mile (5280 feet)

So side BH = the height of the building

tan(HOB) = BH / OB

BH = OB * tan(HOB)
