Answer:
x = 6.6
Explanation:
In order to solve the missing variable, we need to find the scale factor. I'll just take 12.3 and divide it by its corresponding side that is 4.1.
SF = 12.3/4.1 = 3
Now that we know the scale factor is 3, we can take 2.2 and multiply it by 3 to solve for x.
2.2(3) = 6.6
Therefore, x = 6.6.
