In the given right angled triangle,

AC=b=290 cm.

Using trigonometric property in the given triangle,


\begin{gathered} \tan \theta=\frac{opposite\text{ side}}{\text{adjacent side}} \\ \tan 30\degree=(a)/(b) \\ a=b\tan 30\degree \\ a=290*\frac{1}{\sqrt[]{3}} \\ a=167\text{ cm} \end{gathered}

Therefore, the value of a is 167 cm.
