    Setting up the equation you would have: 132 = x + (3x-24)

    Now solve for x:

    132 = x + (3x-24)

    Simplify:

    132 = 4x - 24

    Add 24 to both sides:

    156 = 4x

    Divide both sides by 4:

    x = 156/4

    x = 39

    39

    Step-by-step explanation:

    find angle C by 180-132=48, use the equation 3x-24+x+48=180, to get x=39
