**Steve**, Monday, July 16, 2012 at 10:09amdraw a horizontal line from B to where it intersects the building wall. Call that point C.

Label the top of the building A, and the bottom D.

The height of the building is thus

AD = AC + CD

AC/BC = tan 43°

CD/BC = tan 7°

Now, you see that without knowing the distance BC, there is no way to determine the height of the building. The farther away you are, the higher the building.
