segitiga ABC, sudut C = 600 , sudut B = 450 dan panjang AC = 20 cm. Panjang AB adalah​

Penjelasan dengan langkah-langkah:

Gunakan aturan sinus :

AC/sin(B) = AB/sin(C)

20/sin(45°) = AB/sin(60°)

20/(1/2 √2) = AB/(1/2 √3)

AB = (20 x 1/2 √3)/(1/2 √2)

AB = 10√3/(1/2 √2)

AB = 10√3 x 2/√2

AB = 10√3 x √2

AB = 10√6 cm
