**Damon**, Wednesday, December 28, 2011 at 9:24pmAB/AC = 4/5 so AB = 4 AC/5

AB + AC + 9 = 29

so

AB + AC = 20

4 AC/5 + AC = 20

4 AC + 5 AC = 100

9 AC = 100

etc

**Anonymous**, Friday, February 20, 2015 at 12:34am*The problem should say 29 cm.

AB/AC=4/5, so 4AC=5AB, which is also 4/5(AC)=AB.

AB+BC+AC=29

AB+AC+9=29

AB+AC=20

4/5(AC)+AC=20

9/5(AC)=20

AC=11 1/9

AB=20-AC

AB=20-11 1/9

AB=8 8/9
