Question

the horizontal distance between two towers is 75m and the angular depression of the top of the first tower as seen from the top of the second, which is 160m high , is 45°. find the height of the first tower​

Answer 1

Let AB and CD be the two towers The height of the first tower is AB = 160 m The horizontal distance between the two towers is BD = 75 m And the angle of depression of the first tower as seen from the top of the second tower is ∠ACE = 45° Hence, height of the other tower is 85 m
