Answer:

3,5,7

Step-by-step explanation:

to find which set it is you have to add the first too like this

3+5 >7 if greater than 7 move on too this

5+7>3 if greater move on to this

3+7>5 if greater that means it is a set you can use

3,5,7 is the set of three numbers that could be the side lengths of a triangle. This can be obtained by using the triangle inequality theorem.

What is triangle inequality theorem?

Triangle inequality theorem: The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

If ΔABC is a triangle with sides a, b and c, then it should satisfy the following conditions, a+b>c

                                   b+c>a

                                   a+c>b

Which is the required set of three numbers?

Use the triangle inequality theorem in each set,

  • Set 1: 3,5,9

3+5=8<9, does not satisfy the theorem

  • Set 2: 2,4,6

2+4=6, does not satisfy the theorem

  • Set 3: 2,4,8

2+4=6<8, does not satisfy the theorem

  • Set 4: 3,5,7

3+5=8>7

3+7=10>5

5+7=12>3, this set satisfies the theorem

Hence 3,5,7 is the set of three numbers that could be the side lengths of a triangle.
