Final answer:
In a 30-60-90 triangle, the length of the short leg (opposite the 30-degree angle) is half the length of the hypotenuse. So in this case, the length of the short leg (x) is 4.
Step-by-step explanation:
In a 30-60-90 triangle, the length of the short leg (opposite the 30-degree angle) is half the length of the hypotenuse. So in this case, the length of the short leg (x) is half the length of the hypotenuse (8), which is 4.
