If (3\theta+45^\circ) and (\theta-135^\circ) are coterminal, what is one value of ( \theta )?यदि (3\theta+45^\circ) और (\theta-135^\circ) सहसमापी हैं तो ( \theta ) का एक मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (90^\circ)(90^\circ)
(3\theta+45^\circ-(\theta-135^\circ)=360^\circ) gives (2\theta+180^\circ=360^\circ) and ( \theta=90^\circ ). Keep the difference as a multiple of (360^\circ).(3\theta+45^\circ-(\theta-135^\circ)=360^\circ) से (2\theta+180^\circ=360^\circ) और ( \theta=90^\circ ) है। अंतर को (360^\circ) का गुणज रखें।
