Answer:
x = 4 units
Step-by-step explanation:
2/z = z/6
z² = 12
z = 2√3
using the Pythagorean theorem:
x² = 12 + 2²
x² = 16
x = 4
You're answer is correct. If you round up and estimate to the whole number it would be 9 yards. If you add the total it would 10 yards. You have at least 6 yards so a & b would be out. Then 3/4 three times would be greater then 1/2. So c would be out as well.
The answer is square root of 8
