Answer:
x = 16, y = 8

Explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
 , then
 , then
sin30° = 
 =
 = 
 =
 = 
 ( cross- multiply )
 ( cross- multiply )
x = 16
----------------------------------------------------------
Using Pythagoras' identity in the right triangle
y² + 8² = 16²
y² + 64 = 256 ( subtract 64 from both sides )
y² = 192 ( take the square root of both sides )
y = 
 =
 = 
 = 8
 = 8
