5. Em um polígono, a razão entre a soma das medidas dos ângulos internos e a soma das medidas dos ângulos externos é igual a \( \frac{7}{2} \). Quantos lados tem esse polígono?

In \( \triangle \mathrm{TUV}, u=750 \mathrm{~cm}, v=670 \mathrm{~cm} \) and \( \angle \mathrm{T}=160^{\circ} \). Find the length of \( t \), to the nearest centimeter.

In \( \triangle \mathrm{STU}, u=3.6 \) inches, \( s=7.9 \) inches and \( \angle \mathrm{T}=68^{\circ} \). Find the length of \( t \), to the nearest 10th of an inch.
