Find all solutions to the equation.
\( 2 \sin \theta + \sqrt { 3 } = 0 \)
Write your answer in radians in terms of \( \pi \) , and use the "or" button as necessary. Example: \( \theta = \frac { \pi } { 5 } + 2 k \pi , k \in Z \) or \( \theta = \frac { \pi } { 7 } + k \pi , k \in Z \) this notation
\( \theta = \square\)
