Since we know that triangle inequality theorem states that sum of any two sides of a triangle must be greater than third side.
Now let us see if it is true for our given side lengths.


Now let us try with another pair.


We can see that sum of 5.6 and 4 is less than 10.6. Therefore, 10.6 cm, 5.6 cm and 4.0 cm can not be side lengths of a triangle.
5.268 • 10 to the power of 13
( the decimal point would have to move 14 times to the left)
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
