surveyor wishes to measure the distance across a stream. He sets up his transit at a point C on the bank of the stream, and sights on a point B on the other bank directly opposite him. Then he turns the transit through a right angle, and measures off a distance of 100 feet to a point A. He moves the transit to A, and measures the angle CAB, which he finds to be 50°. How wide is the stream?
