Dear student
The given situation can be represented as,
<img alt="" src=

Let height of the tower be h m
Given, the angles of elevation of the top of tower from the two points are complementary
  ∴ ∠ACB = θ and ∠ADB = 90° – θIn ∆ABC,tanθ=ABBC⇒tanθ=h9⇒h= 9tanθ  
1In ∆ABD,tan90°-θ=ABBD⇒cotθ =h16⇒1tanθ =9tanθ16    using 1⇒9tan2θ=16 ⇒tan2θ=169⇒tanθ=43Height of tower=h=9tanθ    using 1=9×43=12 mNote:tan90°-x=cotx
