Points A and B are on opposite sides of a river. To find the distance between the points, a third point C is located on the same side of the river as point A. The distance between A and C is 43 feet, ∠ACB is determined to be 42° and ∠BAC is 105°. Find the distance between A and B. (Round your answer to one decimal place.)
