is this correct? plz answer only if you know for sure :)

Answer:
x = 36
Step-by-step explanation:
Tan (30) = opposite / adjacent
The opposite is known: it is 12 √3
Tan (30o) = 1 / √3
Tan(theta) = opposite/adjacent.
Opposite = 12[tex]\sqrt{3}[/tex]
Adjacent = x
[tex]\frac{1}{\sqrt{3} } = \frac{12\sqrt{3} }{x}[/tex] Cross multiply
1*x = 12*([tex]\sqrt{3}[/tex])^2
x = 12 * 3
x = 36
