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!
