Aturan sinus

Penjelasan dengan langkah-langkah:

pada  gambar
Δ ABC,  dengan
AC = 9 cm
AB = 12 cm
<B =  30
hitung  sin C

[tex]\sf Aturan \ sinus[/tex]

[tex]\sf \dfrac{AB}{\sin C} =\dfrac{AC}{\sin B}[/tex]

[tex]\sf \sin C = \frac{AB. \sin \ B }{AC}[/tex]

[tex]\sf \sin C = \frac{12. \sin \ 30 }{9}[/tex]

[tex]\sf \sin C = \frac{12.\frac{1}{2}}{9}[/tex]

[tex]\sf \sin C = \frac{6 }{9}= \frac{2}{3}[/tex]
