Question

determine if the side lengths could form a triangle. 8 m, 12 m, 4 m for the first blank, enter the sum of the 2 smaller sides. for the 2nd blank, enter the 3rd side. >

Explanation:

Step1: Identify the two smaller sides

The two smaller sides are \(4m\) and \(8m\).

Step2: Calculate the sum of the two smaller sides

\(4 + 8=12\)

Step3: Compare with the third side

The third side is \(12m\). So we check if \(12>12\) (since the sum of two sides of a triangle must be greater than the third side for a triangle to exist).

Answer:

\(12>12\), and since \(12 = 12\) (not \(12>12\)), these side - lengths \(8m\), \(12m\), \(4m\) cannot form a triangle.
