Answer:
The length of diagonal XU is 6.40 units
Step-by-step explanation:
* Lets explain how to find the distance between two points
- The rule of the distance between two points
and is:
* Lets solve the problem
-From the attached figure:
- The coordinates of the vertex X are (2 , 2)
- The coordinates of the vertex U are (-2 , 7)
∴ The point = (2 , 2)
∴ The point = (-2 , 7)
∴
∴
∵
∴
∵
∴ d = 6.40
* The length of diagonal XU is 6.40 units
