    Answer:

    85º and 95º

    Step-by-step explanation:

    supplementary angle total 180

    (8x – 3) + (7x + 18)  = 180

    Combine like terms

    15x + 15 = 180

    15x = 165

    x = 11

    ———————

    8x – 3

    8(11) – 3

    88 – 3

    85º

    7x + 18

    7(11) + 18

    77 + 18

    95º
