panjang AC = 24 cm BD = 25 cm OB = 16 cm Tentukan panjang AD

Dik : BD = 25, OB = 16, AC = 24

CARI PANJANG OD = 25-16 = 9 DAN PANJANG AO =1/2 X 24 =12

AD = AKAR 12 KUADRAT + 9 KUADRAT
AD = AKAR 144 + 81
AD = AKAR 225
AD = 15 CM

AD^2 = (24 : 2)^2 + (25 : 2) ^2
= 12^2 + 14,5 ^2
= 144 + 210,25
= 354,25

Maaf kalau salah
