The correct Answer is:
To find the value of \(\frac{\tan 25^\circ}{\cot 65^\circ}\), we can follow these steps: ### Step 1: Rewrite \(\cot 65^\circ\) We know that \(\cot \theta = \frac{1}{\tan \theta}\). Therefore, we can rewrite \(\cot 65^\circ\) as: \[ \cot 65^\circ = \frac{1}{\tan 65^\circ} \] ### Step 2: Substitute \(\cot 65^\circ\) into the expression Now, substituting \(\cot 65^\circ\) into the original expression gives us: \[ \frac{\tan 25^\circ}{\cot 65^\circ} = \tan 25^\circ \cdot \tan 65^\circ \] ### Step 3: Use the complementary angle identity We know that: \[ \tan(90^\circ - \theta) = \cot \theta \] Thus, \(\tan 65^\circ\) can be expressed as: \[ \tan 65^\circ = \tan(90^\circ - 25^\circ) = \cot 25^\circ \] ### Step 4: Substitute \(\tan 65^\circ\) back into the expression Now we can substitute \(\tan 65^\circ\) into our expression: \[ \tan 25^\circ \cdot \tan 65^\circ = \tan 25^\circ \cdot \cot 25^\circ \] ### Step 5: Simplify the expression Since \(\tan \theta \cdot \cot \theta = 1\), we have: \[ \tan 25^\circ \cdot \cot 25^\circ = 1 \] ### Final Answer Thus, the value of \(\frac{\tan 25^\circ}{\cot 65^\circ}\) is: \[ \boxed{1} \]
