Answer
$(-0.35021+0.93667i)$
Work Step by Step
cis $110.5^{\circ}=(\cos 110.5^{\circ}+i\sin 110.5^{\circ})$
Using a calculator, we find that $\cos110.5^{\circ}=-0.35021$ and $\sin110.5^{\circ}=0.93667$
Substituting these values in the expression and solving:
$(\cos110.5^{\circ}+i\sin110.5^{\circ})=(-0.35021+0.93667i)$
