A person measures the height of a building by walking out a distance of 40 m from its base and shining a flashlight beam toward the top. When the beam is elevated at an angle of 43.5° with respect to the horizontal, as shown in the figure, the beam just strikes the top of the building. Find the height of the building and the distance the flashlight beam has to travel before it strikes the top of the building. (The...
