You need to know the 30-60-90 triangles rules for lengths. (b, b√3, 2b)

the given side length of corresponds to the 30° angle.  So, b = 8

side y corresponds to the 60° angle so it is b√3. Since we determined that b = 8, then b√3 is 8√3.

side x corresponds to the 90° angle so it is 2b.  Since we determined that b = 8, then 2b = 2(8) = 16

Answer: x = 16, y = 8√3
