Answer 1

Answer:

B)  1 < x < 13

Step-by-step explanation:

use triangle inequality theorem which states that the sum of any two sides must be greater than the third side

let x = third side

6 + 7 > x;    x < 13

6 + x > 7;    x > 1

x + 7 > 6;   x > -1

there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
