Answer:

19, 16, 20

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Aka the highest number - the next highest number = lowest possible number.

3+4 is not greater than 8.

8 + 11 is not greater than 19.

5 + 5 is not greater than 11.

16+19 is greater than 20.

19+20 is greater than 16.

16+ 20 is greater than 19.
