Jawabannya dibawah yah~

Penjelasan dengan langkah-langkah:

1). a).AC = EF = 3,5 cm

DF = BC = 5 cm

b). <E = <A = 80°

<C = <F = 65°

<D = <B = 180 - (80+65)

= 35°

<B = <D = 35°

2). •sisi-sisi yang bersesuaian = CF/CB = EF/AB = CE/AC

•Panjang sisi EF = EF/AB = CF/CB

EF / 8 = 6/(6+4)

EF / 8 = 6 / 10 (kali silang)

10EF =48

EF = 48:10

EF = 4,8 cm

3).AB = √BC x BD

AD = √BD x BC

a). AB =√(16+9) x 9

AB = √25 x 9

AB = √225

AB = 15cm

b). AD =√9 x 16

AD = √144

AD = 12cm

4).EF = 2.3 + 6.8/ 6 +3

= 6 + 48 / 9

= 54/9

= 9cm

5). Tinggi sesungguhnya = 4m (PQ)

Panjang bayangan 1 = 15m (OQ)

Panjang bayangan 2 = 40m (OR)

OQ/OR =PQ/SR

15m/30m = 4m/SR

15 x SR = 4 x 30

15SR = 120

SR = 120:15

SR = 8m
