The inequality that represents possible lengths of the third side is 45 ≥ c ≥ 5
The lengths of the two sides are given as:
20 and 25
Let the third side be c.
The triangle inequality theorem states that:
a + b ≥ c
So, we have:
20 + 25 ≥ c
20 + c ≥ 25
25 + c ≥ 20
Evaluate the inequalities
45 ≥ c
c ≥ 5
c ≥ -5
Remove the negative boundary.
So, we have:
45 ≥ c and c ≥ 5
Rewrite as:
45 ≥ c ≥ 5
Hence, the inequality that represents possible lengths of the third side is 45 ≥ c ≥ 5
