The property you can use here is that no side can be longer than the sum of the other three sides. Thus, the third side must be somewhere between 22 - 5, and 22 + 5 (the "between", in this case, is not inclusive, i.e., it doesn't include the endpoints).

What could be the length of the third side of a triangle that has two sides of lengths 7 and 12?

Oh, what a happy little triangle we have here! To find the possible length of the third side, we can use the triangle inequality theorem. The third side must be greater than the difference between the other two sides and less than the sum of the other two sides. So, the third side could be any length between 5 and 19 units.


The perimeter of a triangle is 57 the first side is twice the length of the second side the third side is seven more than the second side what is the length of each side?

the perimeter of a triangle is 86 inches. the largest side is four inches less than twice the smallest side. the third side is 10 inches longer than the smallest side. what is the length of each side?


Is a 5cm by 12cm a right triangle?

If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.


What could be the length of the third side of a triangle that has two sides of lengths 4 and 15?

For a triangle to exist, the sum of the two shorter sides must be longer than the longest side. If 15 is the longest side, then the other, missing, shorter side must be greater than 15 - 4 = 11. If the third, missing, side is the longest side, then it must be less than 15 + 4 = 19 So the third side is any length greater than 11 and less than 19. Examples include 12, 13, 15, 11.5, 18.5.


Triangle has two sides of length 4 and 15 What value could the length of the third side be?
