Question 58:

Given the line segment AC

As shown:

AB = 2x + 5

BC = 6x - 1

AC = 36

So,


\begin{gathered} AB+BC=AC \\ (2x+5)+(6x-1)=36 \end{gathered}

Solve for x:


\begin{gathered} 8x+4=36 \\ 8x=36-4 \\ 8x=32 \\ x=(32)/(8)=4 \end{gathered}

Substitute with x to find AB

So, the answer will be:

AB = 2x + 5 = 2*4 + 5 = 8 + 5 = 13


AB=13
