Answer:
The value of x,y and z is;
![\begin{gathered} x=5.92 \\ y=7.75 \\ z=9.17 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/udoksa82ln6pmkg67ln62qg44bu4tc157r.png)
Step-by-step explanation:
We want to find the values of x,y and z.
Given the figure in the attached image;
The triangle is divided into two similar triangles and the ratio of their sides will be equal;
![(x)/(5)=(7)/(x)](https://img.qammunity.org/2023/formulas/mathematics/college/o0clnchy536pul0qhioc3yushzzo87swqv.png)
solving for x; cross multiply
![\begin{gathered} x^2=7(5) \\ x^2=35 \\ x=\sqrt[]{35} \\ x=5.92 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/nemx1krrsgpsxypurp56q6gtd8kwomjpyk.png)
To get the value of y and z, we can use Pythagorean theorem or still applt the method above;
![\begin{gathered} (y)/(5)=((5+7))/(y) \\ y^2=5(12) \\ y^2=60 \\ y=\sqrt[]{60} \\ y=7.75 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wrh90ijr0rsatmz967i3h608rjmowvykac.png)
For z;
![\begin{gathered} (z)/(7)=((5+7))/(z) \\ z^2=7(5+7) \\ z^2=7(12) \\ z^2=84 \\ z=\sqrt[]{84} \\ z=9.17 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/m3g0gp6j9kh2kwky9kzrz1wd7ju6vgckag.png)
The value of x,y and z is;
![\begin{gathered} x=5.92 \\ y=7.75 \\ z=9.17 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/udoksa82ln6pmkg67ln62qg44bu4tc157r.png)
