Answer 2

Step-by-step explanation:

Information provided to us-

Height of lighthouse = 100 m

Initial angle of depression = 30°

Final angle of depression = 45°

To find- Distance travelled by the ship

Let AB be the lighthouse, BD be the initial distance between the lighthouse and the ship and BC be the final distance between the lighthouse and the ship.

Please refer to the picture attached for complete solution.

Initial angle of depression = Angle ADB = 30°

Final angle of depression = Angle ACB = 45°

AB = 100 m
