Answer
Explanation:
Step1: Identificar la relación trigonométrica
En un triángulo rectángulo, $\sin(A)=\frac{BC}{AB}$. Sabemos que $BC = 2$ y $A = 63^{\circ}$.
Step2: Re - escribir la fórmula para $AB$
Re - escribiendo $\sin(A)=\frac{BC}{AB}$, obtenemos $AB=\frac{BC}{\sin(A)}$.
Step3: Sustituir valores
Sustituyendo $BC = 2$ y $A = 63^{\circ}$, y sabiendo que $\sin(63^{\circ})\approx0.891$, tenemos $AB=\frac{2}{\sin(63^{\circ})}\approx\frac{2}{0.891}\approx2.2$.
Answer:
$2.2$
