Best ResponseYou've already chosen the best response.0Well, 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)
