Accepted Solution
A:
Answer:6Step-by-step explanation:Let's setup a proportion to find AB.AB corresponds to A'B'.BC corresponds to B'C'.So setting up proportion this would look like:[\tex]\frac{AB}{A'B'}=\frac{BC}{B'C'}[/tex][\tex]\frac{AB}{15}=\frac{3.8}{9.5}[/tex]Cross multiply:[tex]AB(9.5)=15(3.8)[/tex]Divide both sides by 9.5:[tex]AB=\frac{15(3.8)}{9.5)}[/tex]Put into calculator:[tex]AB=6[/tex]
