यदि \(\cot \theta=\frac{12}{5}\) और \(\theta\) प्रथम चतुर्थांश में है, तो \(\cos \theta\) का मान क्या है?
If \(\cot \theta=\frac{12}{5}\) and \(\theta\) is in the first quadrant, what is \(\cos \theta\)?
Explanation opens after your attempt
B. \(\frac{12}{13}\)
Concept
\(In ( \cot \theta=\frac{12}{5}), adjacent is (12), opposite is (5), and hypotenuse is (13). In exams use ( \cos \theta=\frac{\)adjacent}{hypotenuse}).
Why this answer is correct
\(The correct answer is B. (\frac{12}{13}). In ( \cot \theta=\frac{12}{5}), adjacent is (12), opposite is (5), and hypotenuse is (13). In exams use ( \cos \theta=\frac{\)adjacent}{hypotenuse}).
Exam Tip
\(\cot \theta=\frac{12}{5}\) में adjacent (12), opposite (5), hypotenuse (13) है। \(परीक्षा में (\cos \theta=\frac{\)adjacent}{hypotenuse}) लगाएं।
