A triangle can be formed by three line segments with length of 3M, 5M and 16 (M > 0)

A triangle can be formed by three line segments with length of 3M, 5M and 16 (M > 0)

Using the principle that the sum of any two sides of a triangle is greater than the third side, and the difference between the two sides is less than the third side, three inequality equations are listed, and then the intersection is solved
