Answer :
→ θ = 35.9°
Step-by-step explanation :
Given that,
An observer sees a rod 16 m long when it is 18 m from one end and 27 m from the other.
According to the given condition, a triangle is formed with sides :-
Now, we know :
Calculating further :-
∴ The angle of view at which the observer sees a rod 16 m long when it is 18 m from one end and 27 m from the other is 35.9°.
