Perhatikan gambar segitiga ABC berikut ini! A 12√3 cm 30° B C Jika panjang AC 12/3 cm dan sudut C sebesar 30°, tentukan panjang AB

hanifzm AB = X (perumpamaan)
Sin a = depan/miring
= sin 30° = X / 12akar3
= 1/2 = x /12akar3
X = 1/2 . 12 akar 3
= X = 6akar3

Jawaban:

$\frac{12 \sqrt{3} }{sin \: 90} = \frac{c}{sin \: 30}$

$\frac{12 \sqrt{3} }{1} = \frac{c}{0.5}$

$c = 6 \sqrt{3}$

Jadi panjang AB 6√3
