Answer:
6.5 < 3rd side < 19.9.
Step-by-step explanation:
For a triangle, the third side must be more than the difference between the given side lengths, but less than the total of the given side lengths.
So, the third side must be more than...
13.2 - 6.7 = 6.5.
The third side must be less than...
13.2 + 6.7 = 19.9.
6.5 < 3rd side < 19.9.
Hope this helps!
