Jarak BC adalah.. tolong ya poinnya banyak loh 20:)
Jetero
Panjang AB = √(13² - 5²) = √(169 - 25) = √144 = 12 cm
2 x Luas segitiga AOB = Luas Layang2 ACOB 2 x AB x OB / 2 = AO x BC / 2 2 x 12 cm x 5 cm / 2 = 13 cm x BC / 2 120 cm² = 13 cm x BC BC = 120/13 cm = 9,2 cm
= √(13² - 5²)
= √(169 - 25)
= √144
= 12 cm
2 x Luas segitiga AOB = Luas Layang2 ACOB
2 x AB x OB / 2 = AO x BC / 2
2 x 12 cm x 5 cm / 2 = 13 cm x BC / 2
120 cm² = 13 cm x BC
BC = 120/13 cm = 9,2 cm
Semoga membantu :)
