Question

if c lies between a and b on $overline{ab}$, then $ac + cb = ab$. choose the option you can logically conclude about $overline{ab}$. a. $ab = 2(ac)$ b. $ab = 11$ c. $ab = 10.7$ d. none of the above

Explanation:

Step1: Identify given lengths

$AC = 5.5$, $CB=5.2$

Step2: Apply segment - addition postulate

$AB=AC + CB=5.5 + 5.2$

Step3: Calculate AB

$AB = 10.7$

Answer:

C. $AB = 10.7$
