Diana works in a building that is 130 feet tall. She is outside, looking up at the building at an angle of 37° from her feet to
the top of the building. If Diana walks forward and her angle looking to the top of the building changes to 40°, how much closer is she to the building? Round the answer to the nearest tenth of a foot.
