Answer:

A

Step-by-step explanation:

So the whole segment TV is made up of TU plus UV. In an equation:

[tex]TV=TU+UV[/tex]

We already know that TV is 32 and UV is 20. Substitute:

[tex]32=TU+20[/tex]

Subtract 20 from both sides:

[tex]TU=12[/tex]

So, the length of TU is 12.

Our answer is A.

And we're done!
