Question

Kuis +50:
Segitiga siku-siku ABC
siku-siku di B, jika ∠A = ⅙π
dan AC = 2 cm, tentukan
panjang BC

Answer 1

trigonometri∆ABC siku di B∠A = 1/6 π = 180°/6 = 30°AC = 2 cmPanjang BC= AC sin A= 2 × sin 30°= 2 × 1/2= 1 cm

Answer 2

Jawaban:• ABC siku-siku di B ∠A = 1/6 π = 180° /6 = 30°.AC = 2cm Panjang BC: = AC sin A= 2 × sin 30° = 2 × 1/2 = 1cm Jadi, Panjang BC adalah 1cm.
