What's the a answer to this

Step-by-step explanation:

4) ∠ELD + m∠ELG = 180                 linear pair

5)  2x + 124 = 180                            Substitution

6) 2x +124 -124 = 180 -124            Subtraction property

                   2x = 56

7)     2x/2 = 56/2                            Division property

        x = 28

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
