Answer:
x=12
Step-by-step explanation:
The triangle with the x term is a dilation of the smaller triangle. The similar sides of the two triangles have similar terms. The bottom 3 corresponds to the bottom 12, and the side 2 corresponds to the 8. These are both dilations of 4. it is safe to assume that the x term should be 4 times as large as the top 3 on the smaller triangle.
3*4=x
x=12
