Use the image to answer the question.
Two similar isosceles triangles are shown beside one another, triangle A B C and triangle X Z Y. Triangle A B C is larger. Vertices A and X are at the top of their respective triangles. Corresponding vertices are A and X, B and Z and C and Y. Triangles A B C and X Z Y are labeled counterclockwise from the top. Side B C is labeled 12. Side X Z is labeled 6. Side Z Y is labeled 4.
If the scale factor of these two similar triangles is 3, what is the measure of line AB?

The measure of side AB in triangle A B C is 24.
This can be calculated by multiplying the scale factor of 3 by the length of side XZ which is 6.
3 x 6 = 18
Therefore, the length of AB is 24.
