<reasoning>

Identify corresponding parts of congruent triangles

\[

$$\begin{aligned} &\text{Left Triangle: side between right angle and double-arc angle} = 14\\ &\text{Right Triangle: side between right angle and double-arc angle} = 5x + 1\\ &\text{Corresponding sides are equal: } 5x + 1 = 11 \end{aligned}$$

\]

Solve the linear equation for x

\[

$$\begin{aligned} 5x + 1 &= 11\\ 5x &= 10\\ x &= 2 \end{aligned}$$

\]
