Answer:
Yes, because 6+9>12.
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.
so
Applying the triangle inequality theorem
1) [tex]6+9>12[/tex]
[tex]15> 12[/tex] ----> is true
2) [tex]6+12 > 9[/tex]
[tex]18> 9[/tex] ---> is true
3) [tex]9+12>6[/tex]
[tex]21> 6[/tex] ---> is true
therefore
Yes , Mario can make a triangle with these poles
because, the three poles satisfy the triangle inequality theorem
