Question
The distance between two parallel poles is 65√3 m.
The angle of depression of the top of the second pole when seen from the top of first pole is 30°. What will be the height of second pole if the first pole is 110 m long?Solution
Let y be the height of second pole Tan 30° = x/(65√3) 1/√3 = x/(65√3) x = 65 So, y = 110 – 65 = 45 m.
