Best ResponseYou've already chosen the best response.0\[z=r \cos \theta+\iota r \sin \theta \] \[r \cos \theta=2\] \[r \sin \theta=2\sqrt{3}\] square and add \[r^2\left( \cos ^2\theta+\sin ^2\theta \right)=4+4*3=16\] r=4 \[\cos \theta~and~\sin \theta ~are~both~positive.\] \[so~ theta~ lies~in~ first~ quadrant\] divide \[\tan \theta=\sqrt{3}=\tan 60,\theta=60\] z=?
