Question

7 using the segment addition postulate, find the value of the requested line segment.

Explanation:

Step1: Recall segment - addition postulate

If point $U$ lies on line - segment $\overline{TV}$, then $TV=TU + UV$.

Step2: Rearrange the formula to find $TU$

We know that $TV = 17$ and $UV = 12$. Rearranging the formula $TU=TV - UV$.

Step3: Substitute the values

$TU=17 - 12$.

Answer:

$5$
