Answer:

D)

x = 21

y = 7√3

Step-by-step explanation:

One of the sides is 21 (clue from the provided answers).

Using the Pythagorean theorem:

(14√3)² = 21² + side²

588 = 441 + side²

side² = 147

side = 7√3  

Now we have our three sides but, which one is x and which one is y?

try x = 21:

cos 30 = 21/(14√3)

0.8660 = 21/(14√3)

0.8660(14√3) = 21,   yes, then x = 21
