jawab dengan caranya no 5 dan 6

5.
CD bersesuaian dg AC=CD/AC=CD=/CD+AD=6/6+3=6/9=2/3
CE bersesuaian dg BC=CE/BC=CE/CE+BE=CE/CE+5
Jadi,
CD/AC=CE/BC
CD/AC=CE/CE+BE
2/3=CE/CE+5
3×CE=2(CE+5)
3CE=2CE+10
3CE-2CE=10
CE=10 cm

Jawaban
B.10 cm

6.
AC bersesuaian dg EH=AC/EH=14/EH
AB bersesuaian dg EF=AB/EF=20/40=1/2
Jadi,
AC/EH=AB/EF
14/EH=1/2
1×EH=14×2
EH=28

AB bersesuaian dg EF=AB/EF=20/40=1/2
CD bersesuaian dg GH=CD/GH=CD/52
Jadi,
AB/EF=CD/GH
1/2=CD/52
2×CD=1×52
2CD=52
CD=26

Jawaban:
C.28 cm dan 26 cm
