Question

Tolong di jawab ya kak

Answer 1

Soal Pertama :

8/12=DB/DB+3

8DB+24=12DB

24=4DB

6=DB

Jadi panjang AB adalah 6+3=9

Soal Kedua :

EF=(12×2)+(27×4) / 6

EF=22

Answer 2

11. AB/AC = BD/DE

3+x / 12 = x/8

8 (3+x) = 12x

24 + 8x = 12x

24 = 4x

6 = x = BD

AB = 3+x = 3+6 = 9 cm

12. FG/CG = BH/CH

x/4 = 15/6

15.4 = 6x

60 = 6x

10 = x = FG

EF = EG+FG

= 12 + 10

= 22 cm

Semoga membantu ;))
