A. कोई अशून्य कोण संभव नहीं/No non-zero angle is possible
Step 1
Concept
Degree measure is \(x\cdot\frac{180}{\pi}\). \(x\cdot\frac{180}{\pi}=60x\) is possible only for (x=0).
Step 2
Why this answer is correct
The correct answer is A. कोई अशून्य कोण संभव नहीं / No non-zero angle is possible. Degree measure is \(x\cdot\frac{180}{\pi}\). \(x\cdot\frac{180}{\pi}=60x\) is possible only for (x=0).
Step 3
Exam Tip
डिग्री माप \(x\cdot\frac{180}{\pi}\) होता है। \(x\cdot\frac{180}{\pi}=60x\) केवल (x=0) पर संभव है।
Multiply degrees by \( \frac{\pi}{180} \) to convert into radians. In exams identify multiples of \(30^\circ\) quickly.
Step 2
Why this answer is correct
The correct answer is C. \(\frac{5\pi}{6}\). Multiply degrees by \( \frac{\pi}{180} \) to convert into radians. In exams identify multiples of \(30^\circ\) quickly.
Step 3
Exam Tip
डिग्री को रेडियन में बदलने के लिए \( \frac{\pi}{180} \) से गुणा करते हैं। परीक्षा में \(30^\circ\) के गुणकों को जल्दी पहचानें।
\( \frac{37\pi}{15}\times\frac{180^\circ}{\pi}=444^\circ\). If the denominator is (15), use \(180^\circ\div15=12^\circ\).
Step 2
Why this answer is correct
The correct answer is B. \(444^\circ\). \( \frac{37\pi}{15}\times\frac{180^\circ}{\pi}=444^\circ\). If the denominator is (15), use \(180^\circ\div15=12^\circ\).
Step 3
Exam Tip
\( \frac{37\pi}{15}\times\frac{180^\circ}{\pi}=444^\circ\) है। हर (15) हो तो \(180^\circ\div15=12^\circ\) लें।
\( \frac{11\pi}{15}\times\frac{180^\circ}{\pi}=132^\circ\). Calculate \(180^\circ\div15=12^\circ\) and multiply.
Step 2
Why this answer is correct
The correct answer is C. \(132^\circ\). \( \frac{11\pi}{15}\times\frac{180^\circ}{\pi}=132^\circ\). Calculate \(180^\circ\div15=12^\circ\) and multiply.
Step 3
Exam Tip
\( \frac{11\pi}{15}\times\frac{180^\circ}{\pi}=132^\circ\) है। \(180^\circ\div15=12^\circ\) करके गुणा करें।
\( \frac{7\pi}{5}\times \frac{180^\circ}{\pi}=252^\circ\). If the denominator is (5), take \(180^\circ\div 5=36^\circ\).
Step 2
Why this answer is correct
The correct answer is C. \(252^\circ\). \( \frac{7\pi}{5}\times \frac{180^\circ}{\pi}=252^\circ\). If the denominator is (5), take \(180^\circ\div 5=36^\circ\).
Step 3
Exam Tip
\( \frac{7\pi}{5}\times \frac{180^\circ}{\pi}=252^\circ\) है। हर (5) हो तो \(180^\circ\div 5=36^\circ\) लें।
