यदि दो कोण \(20^\circ\) और \(380^\circ\) हैं तो उनका संबंध क्या है?
If two angles are \(20^\circ\) and \(380^\circ\), what is their relation?
Explanation opens after your attempt
Correct Answer
A. वे सह-अंतिम कोण हैंThey are coterminal angles
Concept
\(380^\circ-20^\circ=360^\circ\), so they are coterminal angles. If the difference is a multiple of \(360^\circ\), they are coterminal.
Why this answer is correct
The correct answer is A. वे सह-अंतिम कोण हैं / They are coterminal angles. \(380^\circ-20^\circ=360^\circ\), so they are coterminal angles. If the difference is a multiple of \(360^\circ\), they are coterminal.
Exam Tip
\(380^\circ-20^\circ=360^\circ\) इसलिए दोनों सह-अंतिम कोण हैं। अंतर \(360^\circ\) का गुणज हो तो सह-अंतिम मानें।
