Answer:
k = 13.5 units
Step-by-step explanation:
Look for the similarity ratio.
Side YZ is similar to side BC because 9 is a factor of 3.
Side XZ is also similar to side AC since 12 is a factor of 4.
And the common thing between the factors is that they were both multiplied by 3.
3 × 3 = 9
4 × 3 = 12
So for the last side, which is 4.5, we have to multiply it by 3.
4.5 × 3 = 13.5
