The second one and the last one
Answer:
Yes, the sum of any two sides is greater than the third.
Step-by-step explanation:
To determine whether the provided sides are the sides of a triangle check if the sum of two sides is more than the third side.
The length provided are: 8.5, 13 and 19.1.
- Consider the sides 8.5 and 13:
The sum is:

This sum is greater than the third side 19.1
- Consider the sides 8.5 and 19.1:
The sum is:

This sum is greater than the third side 13
- Consider the sides 13 and 19.1:
The sum is:

This sum is greater than the third side 8.5
Thus, the sides 8.5, 13 and 19.1 are sides of a triangle.
