    x = 18

    Step-by-step explanation:

    Two angles (1) and (2) are supplementary Means m∠ (1) + m∠ (2) = 180

    then

    (7x+2) + (3x-2) = 180

    then

    10x = 180

    then

    x = 18

    Step-by-step explanation:

    since the two angles are supplementary angles they add up to give 180°

    therefore, 7x+2+3x-2=180°

    or, 10x = 180°

    or, x = 18°
