Given x is an integer and \[2<x<7\] We know that for a triangle, sum of two sides is always greater than the third side so, \[x+2>7\] or \[x>5\] We know that x lies between 2 and 7 and just now we found that x>5, so there is only one value for x \[5<x<7=> x=6\] therefore we have only one triangle 2, x=6 and 7
