Given RST similar to UVT
This means the corresponding sides are proportional to each other.
Thus, we can write ratios and solve for the variables.
First,
12 corresponds to 4
x corresponds to 6
We can write a ratio and solve for x:
![\begin{gathered} (12)/(4)=(x)/(6) \\ 4x=6*12 \\ 4x=72 \\ x=18 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/e85509w2c4cuwcl8ci0qtafjr5aeqw7hur.png)
Similarly, we can say:
12 corresponds to 4
y corresponds to 9
We can write a ratio and solve for y:
![\begin{gathered} (12)/(4)=(y)/(9) \\ 4y=9*12 \\ 4y=108 \\ y=27 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/7f5bfvjylc9v65hu5mecx046a6bjqoivlw.png)
