Which of the following pairs of angles represents coterminal angles?

Answer and explanation

Correct answer: \(30^\circ,\ 390^\circ\)

Coterminal angles have the same initial and terminal sides, so their difference must be an integral multiple of \(360^\circ\). Here, \(390^\circ-30^\circ=360^\circ\). Exam tip: subtract the angles first.
