An observer of height h stands on an incline at a distance d from the base of a building of height T. the angle of elevation from the observer to the top of the building is theta and the incline makes an angle of alpha witht he horizontal. Express T, in terms of h, d, theta and alpha. H=6ft, d=50ft, alpha=15 degrees, theta =31.4 degress
