Explanation opens after your attempt
Correct Answer
A. \(45^\circ\) और \(405^\circ\)\(45^\circ\) and \(405^\circ\)
Concept
\(405^\circ-45^\circ=360^\circ\) so they are coterminal. The difference must be a multiple of \(360^\circ\).
Why this answer is correct
The correct answer is A. \(45^\circ\) और \(405^\circ\) / \(45^\circ\) and \(405^\circ\). \(405^\circ-45^\circ=360^\circ\) so they are coterminal. The difference must be a multiple of \(360^\circ\).
Exam Tip
\(405^\circ-45^\circ=360^\circ\) है इसलिए दोनों सहप्रारंभी हैं। अंतर \(360^\circ\) का गुणज होना चाहिए।
