Question

Please Help 7th grade!!

Answer 1

Answer:1,3<x<6,7

Step-by-step explanation: Because there are 2 possible cases based on triangle inequality theorem

1. x is the longest side then we have:

2,7+4>x  ⇒ x<6,7

2. 4 is the longest size then we have:

x+2,7>4 ⇒ x>1.3

Thus, the answer is 1,3<x<6,7
