In which quadrant will the terminal side of (-850^\circ) lie?

Answer and explanation

Correct answer: Third quadrant

The given angle is negative. Add a multiple of 360° to find a coterminal angle: \(-850^\circ+3\times360^\circ=230^\circ\). Since \(180^\circ<230^\circ<270^\circ\), its terminal side lies in the third quadrant. The fourth quadrant contains angles between \(270^\circ\) and \(360^\circ\), so it is not correct. Exam tip: Reduce any angle to a value between \(0^\circ\) and \(360^\circ\) before identifying its quadrant.
