Answer:
Z =7
Explanation:
The middle segment theorem of a triangle says that: A middle segment connecting two sides of a triangle is parallel to the third side and is half its length.
In this case, the middle segment connecting two sides of a triangle is Z.
This means that
![Z = 0.5(14)](https://img.qammunity.org/2020/formulas/mathematics/high-school/7cw1j79ph7y16lgahkwotuqb9a0j3r88hr.png)
Finally we have that:
![Z =7](https://img.qammunity.org/2020/formulas/mathematics/high-school/sfztvj55rdw9gyi5xsm3j95p746xltukqj.png)
The length of the middle segment is 7 units
