Which list could not be the measures of lengths of the three sides of a given triangle?

I cannot give you the answer because you did not upload the list.
However, I can explain how to find the answer so you can solve it yourself:
→The sum of two sides must be greater than (not equal to) the length of the third side for ALL combinations of sides.

a + b > c  must be True
AND
b + c > a  must be True
AND
a + c > b  must be True
 

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
