  • Answer:

    AB = JK = 49

    Step-by-step explanation:

    Since the triangles are congruent,

    AB = JK

    14x+7 = 5x+34

    Subtract 5x from each side

    14x-5x +7 = 5x-5x+34

    9x +7 = 34

    Subtract 7 from each side

    9x+7-7 = 34-7

    9x = 27

    Divide by 9

    9x/9 = 27/9

    x =3

    But we want to know AB

    AB = 14x+7

    AB = 14*3 +7

        = 42+7

        = 49

    AB = JK = 49
