Answer
$-3.2139+3.8302i$
Work Step by Step
$5$ cis $130^{\circ}$=$5(\cos130^{\circ}+i\sin130^{\circ})$
It is known that $\cos130^{\circ}\approx-0.64279$ and $\sin130^{\circ}\approx0.76604$
Substituting these values in the expression and solving:
$5(\cos130^{\circ}+i\sin130^{\circ})\approx5(-0.64279+i(0.76604))\approx-3.2139+3.8302i$
