ngasal direport terima kasih
Jawaban:
a. <AOB / <BOC = Ljuring AOB / Ljuring BOC
120° / 60° = 50 cm² / Ljuring BOC
2 = 50 cm² / Ljuring BOC
Ljuring BOC = 50 cm² / 2
Ljuring BOC = 25 cm²
b. Ljuring BOC = <BOC/360° x L lingkaran
25 cm² = 60°/360° x L lingkaran
25 cm² = 1/6 x L lingkaran
L lingkaran = 25 cm² x 6
L lingkaran = 150 cm²
