Answer
$-110^{\circ}$
Work Step by Step
In order to convert a radian measure to degrees, we must multiply the given radian measure by $\frac{180}{\pi}^{\circ}$ and simplify.
Therefore, $-\frac{11\pi}{18}radians=-\frac{11\pi}{18}(\frac{180}{\pi}^{\circ})=-\frac{1980\pi}{18\pi}^{\circ}=-110^{\circ}$.
