What is the coterminal angle of (750^\circ) between (0^\circ) and (360^\circ)?

Correct answer: \(30^\circ\)

Coterminal angles differ by an integral multiple of \(360^\circ\). Here, \(750^\circ-2\times360^\circ=750^\circ-720^\circ=30^\circ\), so \(30^\circ\) is the required angle. \(60^\circ\) is not coterminal because \(750^\circ-60^\circ=690^\circ\), which is not a multiple of \(360^\circ\). Exam tip: subtract multiples of \(360^\circ\) to reduce an angle to the interval from \(0^\circ\) to \(360^\circ\).
