Answer
$179^{\circ}$
Work Step by Step
Lowest Positive Coterminal Angle: 0$^{\circ}$$\leq$x$\leq$360$^{\circ}$
Since 539$^{\circ}$ is greater than 360, keep subtracting 360 until it satisifies 0$^{\circ}$$\leq$x$\leq$360$^{\circ}$.
539$^{\circ}$ - 360$^{\circ}$ = 179$^{\circ}$, which satisifies 0$^{\circ}$$\leq$x$\leq$360$^{\circ}$
