Multiple choice

A man observes two objects in a straight line in the West. On walking a distance c to the North, the objects subtend an angle $\alpha$, in front of him and on walking a further distance c to the North, they subtend an angle $\beta$. The distance between the objects is $\dfrac{3c}{2 \cot \beta - \cot \alpha}$

  1. True

  2. False

A Correct answer
Explanation

This is a standard problem in trigonometry involving heights and distances. The derivation leads to the distance between objects being c / (cot(beta) - cot(alpha)) or similar forms depending on the geometry. The provided formula is a known result for this specific setup.
