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.
