SOLUTION: A castle has a height of 218M. Given that an unusual bird is 85M away from the foot of the castle. Find the angle of depression of the bird from the top of the castle.

Algebra ->  Trigonometry-basics -> SOLUTION: A castle has a height of 218M. Given that an unusual bird is 85M away from the foot of the castle. Find the angle of depression of the bird from the top of the castle.      Log On

tan(a) = ,   where "a" is the angle of depression.


So, first calculate the ratio  r = 


and then calculate the angle "a":   a = .
