Step 1: The question falls under intersecting secant lines theorem
This explain that m
Step 2 :
[tex]\begin{gathered} 61x+2=\frac{1}{2}(54+194)^{} \\ 61x\text{ + 2 = }\frac{1}{2}\text{ x 248} \\ 61x\text{ + 2 = 124} \\ 61x\text{ = 122} \\ \text{divide both sid}e\text{ by 61} \\ x\text{ = }\frac{122}{61} \\ x=\text{ 2} \\ \end{gathered}[/tex]Then X = 2
