$(0.6537+7.4714i)$
$[2.5(\cos35^{\circ}+i\sin35^{\circ})][3.0(\cos50^{\circ}+i\sin50^{\circ}]$ Using the product theorem, the expression becomes $2.5(3.0)[\cos(35^{\circ}+50^{\circ})+i\sin(35^{\circ}+50^{\circ})]$ Simplifying, $7.5(\cos85^{\circ}+i\sin85^{\circ})$ Using a calculator, $7.5(0.08716+0.99619i)$ Simplifying further, $(0.6537+7.4714i)$
