Define x:
Let the third side be x
The rule of triangle says that the sum of 2 sides must be greater than third side.
Find the possible value of x:
7 + 25 > x
32 > x
x < 32
7 + x > 32
x > 32 - 7
x > 25
25 + x > 7
25 is already greater than 7
From the above, we conclude that 25 > x > 32
⇒ x can be 26, 27, 28, 29, 30 and 31
Answer: x can be 26, 27, 28, 29, 30 and 31
