hitunglah panjang sisi sisi segitiga abc jika sudut A=60° sudut c=90° dan panjang ac=8cm berapa panjang ab dan bc..menggunakan rumus tigonometri

<B = 180 - (90 + 60) = 30°

AC/sin B = AB/sin C
8/sin 30 = AB/sin 90
AB/1 = 8/(1/2)
AB = 16 cm

BC/sin A = AC/sin B
BC/sin 60 = 8/sin 30
BC/(1/2 akar3) = 8/(1/2)
BC = 16 x 1/2 akar3
BC = 8 akar3 cm
