HITUNGLAH NILAI A dan B PADA GAMBAR .. Tolong bantu jawab ini .dikumpulin besok

12/16 = 2a+2/16
3/4 = 2a+2/16
3 x 16 = (2a+2) 4
48 = 8a+8
48-8 = 8a
40 = 8a
40/8 = a
5 = a

12/16 = 2b+1/3+2b+1
3/4 = 2b+1/4+2b
3(4+2b) = 4(2b+1)
12+6b = 8b+4
12-4 = 8b-6b
8 = 2b
8/2 = b
4 = b

*semoga membantu. sukses selalu ^_^

AC = 12 cm + 4 cm = 16 cm
AD = 12 cm
CD = 4 cm
AE = 2b + 1 cm
BE = 3 cm
BC = 16 cm
DE = 2a + 2

- DE
AD/AC = DE/BC
12/16 = DE/16
16DE = 192
DE = 12 cm

- Nilai a
2a + 2 = 12
2a = 12 - 2
2a = 10
a = 5

- AE
AD/AC = AE/AE + BE
12/16 = AE/AE + 3
16AE = 12(AE + 3)
16AE = 12AE + 36
16AE - 12AE = 36
4AE = 36
AE = 9 cm

- Nilai b
2b + 1 = 9
2b = 9 - 1
2b = 8
b = 4

Jadi, nilai a = 5 dan b = 4

Maaf Kalau Salah
