Hi my name is Lawrence and i am in A.P.Calculus. I am a student and i was wondering how to solve this problem.
An observer on level ground is at distance d from a building. The angles of elevation to the bottom of the windows on the second and third floors are a and b respectively. Find the distance h between the bottoms of the windows in terms of a b and d.
