Answer

Explanation:

Step1: Identificar la relación trigonométrica

En un triángulo rectángulo, $\cos\theta=\frac{\text{cateto adyacente}}{\text{hipotenusa}}$. Aquí, $\theta = 57^{\circ}$, el cateto adyacente a $\theta$ es $RT = 5.1$ y la hipotenusa es $ST$. Entonces, $\cos(57^{\circ})=\frac{RT}{ST}$.

Step2: Despejar $ST$

Re - escribimos la ecuación $\cos(57^{\circ})=\frac{5.1}{ST}$ para despejar $ST$. Obtenemos $ST=\frac{5.1}{\cos(57^{\circ})}$.

Step3: Calcular el valor de $ST$

Sabemos que $\cos(57^{\circ})\approx0.5446$. Entonces, $ST=\frac{5.1}{0.5446}\approx9.4$.

Answer:

$9.4$
