Question

Help please I’m stuck

Answer 1

k = 13.5 units

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

Answer 2

12:4=3
9:3=3
so u multiply each side by 3 to get the second triangle..
answer: 4.5*3 =13.5
