Answer:
With those lengths no triangle can be made.
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
In this problem we have
3 feet, 4 feet and 12 feet
Apply the Triangle Inequality Theorem
1) 3+4 > 12
7 > 12 -----> is not true
therefore
With those lengths no triangle can be made.
