Answer:
see the explanation
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the triangle inequality theorem
Let
c ----> the measure of the length of the third side
1) [tex]10+12 > c[/tex]
[tex]22 > c\\c < 22 cm[/tex]
2) [tex]c+10>12[/tex]
[tex]c > 12-10\\c >2 cm[/tex]
so
The solution for the length of the third side is the interval (2,22)
All real numbers greater than 2 centimeters and less than 22 centimeters
