Answer 1

Answer:

Third one

4 + 2.5 > 5

Step-by-step explanation:

To form a triangle, the longest side should be less than the sum of the two shorter sides (triangular inequality)

Longest side < sum of the shorter ones

Longest side: 5

Shorter ones: 2.5 & 4

5 < 2.5 + 4

This is the same as:

4 + 2.5 > 5
