Penjelasan dengan langkah-langkah:
kesebangunan
soal 1
EB/EA = BC/ AD
EB/(EB+ 12) = 6/14
14 EB = 6 (EB + 12)
14 EB = 6 EB + 72
8EB = 72
EB = 9
AE = EB + BA
AE = 9 + 12
AE = 21 cm
soal 2
CD²= AD x SB
CD² = 4 x 16
CD² = 64
CD = √64
CD= 8 cm
soal 3
CB/BD = CA / AE
30/x = (30 + 10) / 28
30/x = 40 / 28
40 x = 30(28)
40 x = 840
x= 840 : 40
x = 21 cm
Jawab:
1.AE = 21 cm
2. cd= 8cm
3.x = 21 cm
