The minimum value of the length of the third side of the triangle must be greater than the difference in the lengths of the known sides. Hmin = 7 – 4 = 3 cm.
The maximum length of the third side of the triangle must be less than the sum of the lengths of the known sides Xmax = 7 + 4 = 11 cm.
The third side value cannot take on the values 3 and 11, since in this case it will be a flat angle.
Hmin> 3 cm.
Hmax <11 cm.
Answer: 3 <X <11.
