An anchor is dropped from a cruise ship at port. The length of the anchors chain is \( 30 m \) below the water. The angle of elevation from the anchor to the ship is \( 39 \) degrees. How many meters did the anchor drop? Round your answer to the nearest tenth.
\( 18.8 m \)
\( 24.2 m \)
\( 47.7 m \)
\( 22.5\)
\(d= 30\sin39= 18.8\)
