PRACTICE IT Use the worked example above to help you solve this problem. A person measures the height of a building by walking out a distance of 49.1 m from its base and shining a flashlight beam toward the top. When the beam is elevated at an angle of 40.5° 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...
