If ( \theta=\frac{5\pi}{18} ), what is its complementary angle in radians?यदि ( \theta=\frac{5\pi}{18} ) है तो उसका संपूरक कोण रेडियन में क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{2\pi}{9} )( \frac{2\pi}{9} )
Complementary angles sum to ( \frac{\pi}{2} ), so ( \frac{\pi}{2}-\frac{5\pi}{18}=\frac{2\pi}{9} ). Use a common denominator before subtracting.संपूरक कोणों का योग ( \frac{\pi}{2} ) होता है इसलिए ( \frac{\pi}{2}-\frac{5\pi}{18}=\frac{2\pi}{9} ) है। समान हर बनाकर घटाएं।
