यदि \( \theta \) और \( \phi \) सहसमापी हैं तथा \( \theta=5x+20^\circ \) और \( \phi=x+380^\circ \) है तो (x) का मान क्या है?
If \( \theta \) and \( \phi \) are coterminal and \( \theta=5x+20^\circ \), \( \phi=x+380^\circ \), what is the value of (x)?
Explanation opens after your attempt
D. \(90^\circ\)
Concept
For coterminal angles the difference can be \(360^\circ\), so \(5x+20^\circ=x+380^\circ\) gives \(x=90^\circ\). Form a linear equation.
Why this answer is correct
The correct answer is D. \(90^\circ\). For coterminal angles the difference can be \(360^\circ\), so \(5x+20^\circ=x+380^\circ\) gives \(x=90^\circ\). Form a linear equation.
Exam Tip
सहसमापी होने पर अंतर \(360^\circ\) हो सकता है इसलिए \(5x+20^\circ=x+380^\circ\) से \(x=90^\circ\) है। रैखिक समीकरण बनाएं।
