According to the picture, the proportion that exists between the sides of the triangles is:


\begin{gathered} (3x+10)/(60)=(1)/(2) \\ \end{gathered}

From this proportion, clear x:


\begin{gathered} (3x+10)/(60)=(1)/(2) \\ 3x+10=(60)/(2) \\ 3x=30-10 \\ x=(20)/(3) \end{gathered}

x has a value of 20/3
