यदि \( \theta=\frac{5\pi}{18} \) है तो उसका संपूरक कोण रेडियन में क्या है?
If \( \theta=\frac{5\pi}{18} \), what is its complementary angle in radians?
Explanation opens after your attempt
Correct Answer
A. \( \frac{2\pi}{9} \)
Concept
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.
Why this answer is correct
The correct answer is A. \( \frac{2\pi}{9} \). 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.
Exam Tip
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।
