To find the height of a building, a person walks 75 feet from the base of the building. They measure an angle of 47° between a line of sight to the top of the building and the ground. Find the height of the building. NOTE: If you want to calculate a trig function in degrees in Geogebra, enter the trig function, write angle and then type deg. For example sin(80°) would be entered as sin(80 deg). The height of the bulding is
