33. A surveyor wants to approximate a river's width. As shown in the figure, below, points A and C are located on the west bank of a river and point B is located on the east bank of the river such that ∠ACB is a right angle. She measures and finds that the length of AC is 54 meters and the measure of ∠BAC is 68°.

Given the trigonometric approximations in the tables below, which of the following is closest to the river's width, in meters, represented by the length of BC ?
