Answer:
t = 6.5
Step-by-step explanation:
Since triangle ABC and triangle XYZ are similar, the ratio of the corresponding sides is constant.
Then, AB and XY are corresponding and AC and XZ are corresponding, so
![\begin{gathered} (AB)/(XY)=(AC)/(XZ) \\ (19.5)/(t)=(13.5)/(4.5) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/l0gkbc448bo14kbw2u0qm3myg9opwpy9vu.png)
To solve for t, we need to cross multiply, so
![\begin{gathered} 19.5(4.5)=13.5t \\ 87.75=13.5t \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ggcvkqgyygk3ndxs649ranqk15m9hffm0t.png)
Divide both sides by 13.5
![\begin{gathered} (87.75)/(13.5)=(13.5t)/(13.5) \\ 6.5=t \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ygwsnl3jq3kz1ng1fd1eout1ojtlyfqqok.png)
Therefore, t = 6.5
