Question

Bella is making a sculpture. she has pieces of copper pipe that are 4 centimeters long and 13 centimeters long.what is a possible third length of copper pipe that will make a triangle?

Answer 1

Answer: The possible length of the third triangle is 17

Step By Step Explanation: When you add 4 + 13 = 17 and 4 and 13 were the lengths of the other copper pipes.

Answer 2

Explanation:

A possible third length of the copper pipe that will make a triangle is 17 centimeters long.

This can be determined by using the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For example, if the 4 cm pipe represents one side and the 13 cm pipe represents another side of the triangle, in order to make a triangle, the third side must be less than the sum of the other two sides (4 cm + 13 cm) and greater than the difference of the other two sides (13 cm - 4 cm). Therefore, the third side must be between 9 cm and 17 cm.

17 cm is the only length within this range that can make a triangle with 4 cm and 13 cm.
