Question

Determine if the side lengths could form a triangle. Use an inequality to justify your answer.16 m, 21 m, 39 m

Answer 1

We can draw the following triangle

the triangle inequality state that

[tex]|a-b|where | | is the absolute value. In our case, if we apply this inequality we obtain[tex]|21-39|which gives[tex]\begin{gathered} |-18|since 21m is between 18m and 60m, the values 16m, 21mn and 39m can form a triangle.
