Answer:

5

Step-by-step explanation:

AC = AB + BC

16 = x+1 + x+7

Combine like terms

16 =2x+8

Subtract 8 from each side

16-8 = 2x+8-8

8 = 2x

Divide by 2

8/2 = 2x/2

4 =x

We want to find AB

AB = x+1 = 4+1 = 5
the measuring is equal to 5 do to the whole length being 16 when adding the two equations together and equaling it to 16 you can solve the equation to equal 5.
