Question

A , B , C are point's on a line with AB= 5.1 in and BC= 2.6 in. What is the length of AC?

Answer 1

7.7 in

Step-by-step explanation

Step 1

Let

AB=5.1( black)

BC=2.6(red)

AC=?

AC is the line that goes from A to C, (blue)

Also

`AC=AB+BC`

Step 2

replace

`\begin{gathered} AC=AB+BC \\ AC=5.1+2.6 \\ AC=7.7 \end{gathered}`

so, the answer is 7.7
