Answer 1

B) 1 < x < 13

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
