Respuesta :

[tex]\begin{gathered} \angle A+\angle B+\angle C=180 \\ \angle B=180-\angle A-\angle C \\ \angle B=180-33-87 \\ \angle B=60 \end{gathered}[/tex]

Now, using sine law:

[tex]\begin{gathered} \frac{3}{\sin(B)}=\frac{x}{\sin (A)} \\ \frac{3\cdot\sin (33)}{\sin (60)}=x \\ x=1.89 \end{gathered}[/tex]
