You are standing at a point 125 feet from the base of a building. The angle of elevation to the top of the building is 63.

Question

How tall is the building and what is the distance to your friend who is standing at the top of the building?

Answer 1

This question was answered already.  Here is the answer again.

 

h = height of building
b = 125 ft
θ = 63°

Note that

h/b = tanθ ⇒

h = b tanθ = (125 ft) tan63° = ?

Distance to friend is the hypotenuse of a right triangle.

d = √(b² + h²)

Just plug in the numbers and get d in ft.
