Which is the possible length of the third side of a triangle given the first two sides are 5 cm and 18 cm
To find the possible length of the third side of a triangle given the first two sides are 5 cm and 18 cm, we can use the triangle inequality theorem.
According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
So, in this case, the possible length of the third side must satisfy the condition that:
18 cm - 5 cm < third side < 18 cm + 5 cm
13 cm < third side < 23 cm
Therefore, the possible length of the third side of the triangle can be any value between 13 cm and 23 cm.
