Determine the possible side lengths of the third side of a triangle with known side lengths 3 and 6. answers: –3 < c < –9
vovangra [49]

Answer:

3 < c < 9

Step-by-step explanation:

The length of a side of a triangle cannot be negative. This eliminates the first and last options.

The addition of two sides of a triangle must be greater than the third side. In this case:

3 + 6 = 9 > c

So, the second option is correct. The third option is not correct, because, for example, c = 8 is possible
