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).
