Recall that in a right triangle we know that:

$\tan \theta=\frac{\text{opposite leg}}{adyacent\text{ leg}}.$

Therefore:

$\tan 29^(\circ)=(x)/(15).$

Multiplying the above equation by 15 we get:

$\begin{gathered} \tan 29^(\circ)*15=(x)/(15)*15, \\ x=15\tan 29^(\circ)\text{.} \end{gathered}$

Answer:

$x=15\tan 29^(\circ).$
