In the figure below, points A and B are on opposite banks of a small stream. Point C is on the same bank of the stream as point B and approximately 18 meters from B. The measure of angle CBA is 45°, and the measure of angle BCA is 60°.

Which of the following expressions gives the approximate distance, in meters, between point A and point B ?
(Note: For triangle PQR, where p, q, and r are the lengths of the sides opposite angle P, angle Q, and angle R, respectively, sin(P) / p = sin(Q) / q = sin(R) / r)
