Their allotted time is up, so they make their way back to the
dock. The westernmost personal watercraft, labeled "Jared"
below, travels at an angle of 74° in reference to the
easternmost personal watercraft's position, labeled "Tyler"
below, who is 240 yards away from the dock. If the
trajectory of each personal watercraft forms an 82° angle
at the dock, how far apart are Jared and Tyler?
