    the angles are 66 and 114

    Step-by-step explanation:

    supplementary angles add to 180

    x+7 + (2x-4) = 180

    combine like terms

    3x+3 = 180

    subtract 3 from each side

    3x+3-3 = 180-3

    3x = 177

    divide by 3

    3x/3 = 177/3

    x = 59

    x+7 = 59+7 = 66

    2x-4 = 2 (59) - 4 = 118 - 4 = 114
