The shadow of a flagpole in a school is 1/√3 times its height. The angle of elevation of the sun is:

• A. tan⁻¹(1/√3)
• B. cot⁻¹(1/√3)
• C. sin⁻¹(1/√3)
• D. cos⁻¹(1/√3)

Answer: B) cot⁻¹(1/√3)

Explanation: tan(θ) = height / shadow = h / (h/√3) = √3. This means cot(θ) = 1/√3, so θ = cot⁻¹(1/√3), which is 60°.
