$-180˚$

There is a simple rule that can be used when converting from a measure in radians to an equivalent measure in degrees.

The rule is:

$"radians"xx(180˚)/pi="degrees"$

So to convert the given radian measure:

$"degree measure"=-pixx(180˚)/pi$

The $pi$ in the numerator will cancel with the $pi$ in the denominator. The minus sign will stick around leaving:

$-180˚$
