Answer:
29
Step-by-step explanation:
We can solve this using the triangle inequality theorem:
For any given triangle, the sum of two sides of a triangle is always greater than the third side.
The sum of these two sides is:
[tex]18+12=30[/tex]
So the third side can be any number less than 30. The greatest of these numbers is thus, 29.
Answer:12
Step-by-step explanation:
because if you have one side that's 18 and another is 12 than the lower number is the other side .
