The distance between tree and tower is 30√3 m

Step-by-step explanation:

Given that

  • Height of tower (H) = 30 m

          Distance between from base of tree to tower = B = Unknown
            Angle of depression (∠α) = 30°

  • We know that

         Angle of elevation = Angle of depression

        Angle of elevation = ∠α      
        Angle of elevation =  30°

 
Now from trigonometric relation

   
 tan @ = H|B

tan 30 = 30|B

[tex]\sqrt[1]{3}[/tex] = 30|B
