The angle of elevation of the Sun, when the length of the shadow of a tree is $\sqrt{3}$ times the height of the tree, is:
Answer & explanation
Correct answer: option 1
Let the length of the tree be 1 unit
Length of shadow = √3 times length of the tree = √3 unit
Tan θ = Perpendicular / Base = 1 / √3
Tan θ = Tan 30°
∴ θ = 30°
