Answer 8

Sorry it took me so long! I had to make dinner for the family! Ok, but I'm here to help you now. When you are looking for similarity, you need to set up proportions. Side of one shape to the corresponding side of the other. Here your ratio is \[\frac{ 12 }{ 40 }=\frac{ 3 }{ x }\]Because there is an equals sign in between the fractions, you can cross multiply to solve for x. That's 12x = 120. x = 10.
