Question

If B is the midpoint of ac and the length of ac is 23.8, what is the length of ab A. 11.7 B. 11.9 C. 12.4 D. 19.1

Answer 1

Well, the midpoint simply means the point right half-way between both endpoints, thus is just half that or ab = 23.8/2.

Answer 2

Answer:

Option B:11.9

Step-by-step explanation:

We are given that B is the mid point of AC.

Length of AC=23.8 units

We have to find the length of AB.

We know that when B is the mid point of AC then

AB=BC

AB+BC=AC

By using segment addition property

Let AB=x

Then , BC=x

Substitute the values then we get

$x+x=23.8$

$2x=23.8$

$x=\frac{23.8}{2}$

$x=11.9$

Hence, length of AB=11.9 units

Option B is true.
