Step-by-step explanation:
<u>Given sides of a triangle:</u>
<u>Triangle inequality theorem:</u>
- Any side is smaller than the some of the other two.
<u>Apply to the given triangle:</u>
- 2x + 5 - x > 4 ⇒ x > -1
- 2x + 4 > 5 - x ⇒ 3x > -1 ⇒ x > -1/3
- 5 - x + 4 > 2x ⇒ 3x < 9 ⇒ x < 3
<u>Combine all the inequalities:</u>
- -1/3 < x < 3
- x = (-1/3, 3)
