Gerard is a window washer who charges his clients based on the area to be washed. He knows the width of an office tower, but he also needs the height. Although he dressed up as Spiderman at Halloween, he canāt crawl up the outside of buildings. This means that he canāt just use a tape measure to determine the buildingās height. He could, however, stand on the roof of an adjacent building and determine the height indirectly using trigonometry. So, from the top of the adjacent building 42 m away, Gerard uses a clinometer and determines that the angle of depression to the base of the office tower is 38Ā° and the angle of elevation to the top of the office tower is 52Ā°. How tall, to the nearest meter, is the building whose windows he may wash?
