Tentukan nilainya...tolong dijawab,utk saya koreksi dgn jawaban saya. terima kasih

Answer 1

Gambar 1 :
CD / AD = CE /EB
9 / 3 = 12 / P
P = 3 × 12 ÷ 9
P = 36 ÷ 9 = 4 cm
gambar 2 :
C / C+D = E / F
6 / 6+4 = 3 /F
6 /10 = 3 /F
F = 10 × 3 ÷ 6
F = 30 ÷ 6 = 5 cm
gambar 3:
AE / EC = AD / DB
x / 2 = 6 /4
x = 2×6 ÷ 4
x = 12 ÷ 4 = 3 cm
AE / EC+AE = ED / CB
3 /2+3 = x / 10
3 /5 = x / 10
x =3 × 10 ÷ 6 =30 ÷ 6 = 5cm
ma'af kalau salah
