Question

If B is the midpoint of AC and the length of AC is 23.8 what is the legength of AB

Answer 1

Hey there,

So explain and to illustrate (how $B$ is the midpoint of $AC$ and the length of $AC$ is 23.8 what is the length of $AB$

                                       A-----------------B----------------C

So, $\boxed{AC}$ in the problem here is to be considered the (Whole area of this line). $AC$ is the whole thing. 

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is $AB$, so we will find the one half of it, which in this illustration is to be considered $AB$

23.8 ÷ 2 = $\boxed{11.9}$

$\boxed{AB=11.9}$

Hope this helps.
