    The correct answer is 82

    Step-by-step explanation:

    1st piece=x

    2nd piece=3x+3

    3rd piece=4x-8

    Combine like terms:

    x+3x+4x=8x

    3-8 = - 5

    8x-5=175

    8x-5+5=175+5

    8x=180

    x=22.5

    1st piece=22.5 in

    2nd piece=70.5 in

    3rd piece = 82

    3rd piece is the biggest, so the correct answer is 82
