Question

The shadow of a tree is root 3 times its height find the angle of elevation of the sun

Answer 1

height= x : height

shadow=√3x : base

angle=Δ

tanΔ= x/√3x  

            = 1/√3                                       we know that  tan  30 = 1/√3

  ∴Δ or angle of elevation is equal nto 30.
