The angle of elevation of the top of a tower from a point on the ground, which is 30m away from the foot of the tower is 30 ∘ . Find the height of the tower. Options: A . &nbsp 10 √ 3 m B . &nbsp 20 √ 3 m C . &nbsp 30 √ 3 m D . &nbsp 20 m

Answer: Option A : A Angle of elevation = θ = 30 ∘ ⇒ t an θ = P e r p e n d i c u l a r B a s e ⇒ tan θ = h 30 ⇒ tan 30 ∘ = 1 √ 3 ⇒ h 30 = 1 √ 3 Therefore, h = 10 √ 3 m .
