Step-by-step explanation:

For the left triangle:

leg/12 = (12+x)/leg

leg = 13


\begin{gathered} (13)/(12)=(12+x)/(13) \\ \end{gathered}
\begin{gathered} \text{cross multiply:} \\ 13(13)\text{ = 12(12+x)} \\ 169\text{ = 144 + 12x} \end{gathered}
\begin{gathered} 169-144\text{ = 12x} \\ 25\text{ = 12x} \\ (25)/(12)=(12x)/(12) \\ x\text{ = 2.08} \end{gathered}

z = x + 12

z = 2.08 + 12

z = 14.08

For the right triangle:

leg/z = x/leg

leg = y

y/14.08 = 2.08/y
