5Bii A group of civil engineers wants to build a bridge over a canyon, but they do not know how wide the canyon is. They raise different tall objects up beside the canyon until one of them casts a shadow to the other side of the canyon. The height of the object is 800 ft and they estimate the angle of elevation of the sun is 65. Roughly, how wide is the canyon?
