To indirectly measure the distance across a river, Daniel stands on one side of the river and uses sight-lines to a landmark on the opposite bank. Daniel draws the diagram below to show the lengths and angles that he measured. Find PR, the distance across the river. Round your answer to the nearest foot. 235 ft 140 ft 330 ft (Diagram is not to scale.)
