Special right triangles!!! Help

Answer:
This is a 30, 60, 90, right triangle.
The length of the longest side (this case s), is equal to twice the length of the shortest side.
x[tex]\sqrt{3\\}[/tex] = 27
x = 27/[tex]\sqrt{3}[/tex]
s is twice as that, so the answer is 54/[tex]\sqrt{3}[/tex]
Let me know if this helps!
