If the two sides of a triangle are 5 cm and 8 cm long respectively, how many cm (whole centimeter) may the other side be

If the two sides of a triangle are 5 cm and 8 cm long respectively, how many cm (whole centimeter) may the other side be

The sum of the two sides of the triangle is greater than the third side, and the difference between the two sides is less than the third side,
So 8-5 < a < 8 + 5
3＜a＜13.
Where: B = 5, C = 8

The two sides of a triangle are 5cm and 8cm respectively. How long is the third side?
Such as the title
Why should it be bigger than 9 and smaller than 13?

More than 3 less than 13

The perimeter of the triangle vegetable field is 168 meters, the ratio of side length is 4:3:5, and the longest side length is 5______ Rice

4 + 3 + 5 = 12168 × 512 = 70 (m) a: the longest side is 70 M
