Given:

Meridian of a man = 6 anxiety

Superlative of pillar = 24 anxiety

Formula Used:

tan(90° - θ) = cot θ

tan θ = Perpendicular/Base of operations

cot θ = Base/Perpendicular

Complementary angle: The sum of 2 angles is equal to 90 degrees, they are chosen complementary angles.

Adding:

Let assume the angle of elevation = θ

So, the bending of low = (ninety° - θ)

DA = BC = vi anxiety

BE = BC + CE

⇒ 24 feet = 6 feet + CE

⇒ CE = 18 feet

∠EDC = θ

DC ∥ AB and DC = AB

∠CDB = ∠DBA = (xc° - θ)

ΔDEC

tan θ = EC/DC

⇒ tan θ = xviii/DC .......................(1)

ΔDBA

tan(90° - θ) = DA/AB

⇒ cot θ = six/DC ..........................(ii)

Equation (1) × Equation (ii)

⇒ tan θ × cot θ = 6/DC × 18/DC

⇒ 1 = 108/(DC)^two

⇒ DC = 6√iii feet

⇒ DC = AB = 6√iii feet

∴The distance of the human being from the pillar is 6√iii feet.

The right option is 2 i.e. 6√iii anxiety
