    Side inequality of triangle says that the sum of any two sides of a triangle has to be greater than the third side so the sum of two given sides i.e. 11 + 18 = 29 > 3rd side So 29 > 3rd side or we can say 3rd side < 29 Also, the third side cannot be smaller than the difference of the given two sides so the third side has to be greater than 18-11 = 7 so 3rd side > 7 so if length of 3rd side is represented by x, then 7 < x < 29
