The following triangles are similar. Find side AB.
2
4
10
12

Answer:
4
Step-by-step explanation:
Set up ratios of corresponding sides. x+2 is to 6 as 2 is to 3:
[tex]\frac{x+2}{6}=\frac{2}{3}[/tex]
Now cross multiply to get
3(x + 2) = 12 and
3x + 6 = 12 so
3x = 6 and
x = 2. That means that side AB, x + 2, is 2 + 2 which is 4
