Answer:
x= any value bigger than 5/3 but smaller than 6
I could be 1 or 3, or 4....
5/3<x<6
Step-by-step explanation:
According to triangle inequality theorem, for any given triangle, the sum of two sides of a triangle is always greater than the third side.
(x+11) +(2x+10)>(5x-9)
6>x ( x less than 6)
(x+11)+(5x-9)>(2x+10)
x>2 (x more than 2)
(2x+10)+(5x-9)>(x+11)
x> 5/3 (x more than 5/3)
