Do you have a shortcut solution to this?

anonymous · Answer

answer is 18

hero · Answer

I guess that answers the question, but what are the shortcut steps?

anonymous · Answer

answer is always between 13+29 and 29-13

Well the biggest the third side could be would be JUST UNDER (13 cm + 29 cm). The smallest the third side could be would be JUST OVER (29 cm-13 cm).  

That's because the sum of the shortest sides of the triangle must be LONGER than the third side. 

Think of it this way.  If you have a 1 foot ruler and a one foot ruler, can you connect them to stretch any longer than 3 feet?
