A river is flowing from west to east. For determining the width of the river two points (A) and (B) are selected on the southern bank such that distance AB is 75 m and point (A) is westwards. Point (C) is selected on the northern bank in such way that angles (CAB) and (CBA) are 52° and 68° respectively. Calculate the river width. Additionally, if a ship blocks the navigation in the river as the ship bow is rested on point (C) and the stern is rested on point (D) which is located in between points (A) and (B) and 25 m away from point (B), calculate the ship length.

Question

A river is flowing from west to east. For determining the width of the river two points (A) and (B) are selected on the
southern bank such that distance AB is 75 m and point (A) is westwards. Point (C) is selected on the northern bank in
such way that angles (CAB) and (CBA) are 52° and 68° respectively. Calculate the river width. Additionally, if a ship
blocks the navigation in the river as the ship bow is rested on point (C) and the stern is rested on point (D) which is
located in between points (A) and (B) and 25 m away from point (B), calculate the ship length.
