A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is A = 65°. He then walks s = 130 feet further away and observes that the angle of elevation to the top of the antenna is B = 48° (see the figure below). Find the height of the antenna to the nearest foot. (Hint: Find x first.)
