Verified Solution

Answer & Solution

Correct Answer

(D) \(\frac{7}{24}\)

Step-by-step Solution

Detailed explanation

\(\text{Let } \theta = \cos^{-1} \frac{7}{25}\). \(\cos \theta = \frac{7}{25}\). \(\text{Opposite side} = \sqrt{25^2 - 7^2} = \sqrt{625 - 49} = \sqrt{576} = 24\). \(\cot \theta = \frac{\text{Adjacent}}{\text{Opposite}} = \frac{7}{24}\).
