Tolong dibantu yaaa besok dikumpulin

1. <AOB / <BOC = panjang busur AB / panjang
busur BC
= 60 / 150 = 10 / panjang busur BC
= panjang busur BC = 150×10 / 60
= panjang busur BC = 25 cm



2. <FOE / <GOH = luas juring OFE / luas juring
OGH
= 70 / 80 = 91cm^2 / luas juring OGH
= luas juring OGH = 91cm^2×80 / 70
= luas juring OGH = 7280cm^2 / 70
= luas juring OGH = 104cm^2


Maaf kalo salah
