So, the object is 59.30 m from the base of the cliff.




               Example 2- In the Figure, AB is a 6 m high pole and CD is a ladder inclined at
               an angle of 60° to the horizontal and reaches up to a point D of pole. If AD =
               2.54 m, find the length of the ladder. (use √3=1.73)

               Solution-












               Solution:

















               Example 3- The angles of depression of the top and bottom of a 50 m high
               building from the top of a tower are 45° and 60° respectively. Find the height of
               the tower and the horizontal distance between the tower and the building,
