A CCTV camera is on a 10m pole at a shop. It targets a till 10m away from the pole's base. The angle of depression is:
- A. tan⁻¹(0.5)
- B. tan⁻¹(1)
- C. sin⁻¹(1)
- D. cos⁻¹(1)
Answer: B) tan⁻¹(1)
Explanation: tan(θ) = opposite / adjacent = 10 / 10 = 1. Angle of depression equals angle of elevation, so tan⁻¹(1) = 45°.
