3)
Apply LAW OF SINES
[tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]
Replace with the values given:
[tex]\frac{18}{sin\text{ }112}=\frac{8}{sin\text{ }x}[/tex]
Cross multiply
[tex]18(sinx)=8(sin112)[/tex][tex]18(sinx)=7.4[/tex][tex]sinx=\frac{7.4}{18}[/tex][tex]x=arcsin(\frac{7.4}{18})[/tex]
Answer:
x = 24.3
