A water tower is located 356 feet from a building. From a window in the building, an observer notes that the angle of elevation to the top of the tower is 36° and that the angle of depression to the bottom of the tower is 24°. How tall is the tower? height = feet. How high is the window from the ground? window is feet above the ground.
