two sides of traingles have the following measures. Find the range of possible measures for the third side. 7,10

THANKS!

well if it were longer than 7 + 10 , then those two sides would not reach the ends of it even if they were in a straight line.

and if it were smaller than 10 - 7 then you would have a similar impossible situation with it not being able to stretch between the ends even if the 7 and 10 were sitting on top of each other.
