    x = 71.6

    Step-by-step explanation:

    Supplementary angles add to 180 degrees

    Let the unknown angle be x

    x+108.4 = 180

    Subtract 108.4 from each side

    x+108.4-108.4 = 180-108.4

    x = 71.6

    Supplementary angles are two angles that add up to 180 degrees. We can subtract to find the other angle.

    180 - 108.4 = 71.6 degrees

    The second angle is 71.6 degrees.

    Best of Luck
