Final answer:
The length of WX is approximately 4.24 units.
Step-by-step explanation:
To find the length of WX, we can use the distance formula. The distance formula is given by:
d = √((x2 - x1)² + (y2 - y1)²)
Substituting the given values, we have:
d = √((5 - 2)^2 + (-4 - (-7))²)
d = √(3^2 + 3^2)
d = √(18)
d = 3√(2)
The length of WX is approximately 4.24 units.
