[Solved] Let \(z _ { 1 } = 2 \left( \cos \frac { 5 \pi } { 6 } + i \sin \frac { 5 \pi } { 6 } \right)\) and \(z _ { 2 } = 5 \left( \cos \frac { \pi } { 3 } + i \sin \frac { \pi } { 3 } \right)\) . Find \(Z _ { 1 } Z _ { 2 }\) Times Interest Earned Ratio: A financial metric that measures a company’s ability to meet its debt obligations by comparing its income before interest and taxes to its interest expenses.
