If ( \theta ) and ( \phi ) are coterminal and ( \theta=5x+20^\circ ), ( \phi=x+380^\circ ), what is the value of (x)?यदि ( \theta ) और ( \phi ) सहसमापी हैं तथा ( \theta=5x+20^\circ ) और ( \phi=x+380^\circ ) है तो (x) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (90^\circ)(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.सहसमापी होने पर अंतर (360^\circ) हो सकता है इसलिए (5x+20^\circ=x+380^\circ) से (x=90^\circ) है। रैखिक समीकरण बनाएं।
