A pipeline is to be constructed between points A and B on opposite sides of a river, as shown in the figure. To determine the amount of pipe needed, using a theodolite at point A, a right triangle ACB is constructed with point C approximately 120 feet from A. At point A, the transit is used to determine that the angle F is 40°. Determine the amount of pipe needed to connect points A and B. (Round your answer to one decimal place.)
