Geometry ? ? find the value of each variable leave your answer in simplest radical form. explain if you can

So   hmm notice the picture below

so.. as you can see, using the 30-60-90 ratios, what the values of "x" is

for example, in the first one, if x = 2, then the shorter side is 2, and the longer one is is 2√(3)

and so on, surely you can get the ones in 8) and 9)
