$RS= 3\sqrt 2 \approx 4.24$ $ST= 3\sqrt 2\times\sqrt 3 \approx 7.34$

Work Step by Step

In △RST $\angle STV=150^{\circ}$ So $\angle STR=180-150=30^{\circ}$ because supplementary angles So $\angle SRT= 60^{\circ}$ now By Theorem 5.5.2/ (30-60-90 Theorem) $RT=6\sqrt 2$ given $RS= 3\sqrt 2 \approx 4.24$ $ST= 3\sqrt 2\times\sqrt 3 \approx 7.34$
