यदि \(\frac{3x\pi}{20}\) रेडियन \(81^\circ\) के बराबर है, तो (x) का मान क्या होगा?
If \(\frac{3x\pi}{20}\) radians equals \(81^\circ\), what is the value of (x)?
Explanation opens after your attempt
Correct Answer
B. (3)
Step 1
Concept
\(81^\circ=\frac{9\pi}{20}\), so \(\frac{3x\pi}{20}=\frac{9\pi}{20}\) gives (x=3). In exams, write both angles in the same unit.
Step 2
Why this answer is correct
The correct answer is B. (3). \(81^\circ=\frac{9\pi}{20}\), so \(\frac{3x\pi}{20}=\frac{9\pi}{20}\) gives (x=3). In exams, write both angles in the same unit.
Step 3
Exam Tip
\(81^\circ=\frac{9\pi}{20}\), इसलिए \(\frac{3x\pi}{20}=\frac{9\pi}{20}\) से (x=3)। परीक्षा में दोनों कोणों को समान इकाई में लिखें।
