    Linear pair are two angles that are adjacent (share a leg) and supplementary (add up to 180°).

    We have m∠1 = x - 33 and m∠2 = x + 71. Make and solve the equation:

    (x - 33) + (x + 71) = 180

    (x + x) + (-33 + 71) = 180

    2x + 38 = 180 subtract 38 from both sides

    2x = 142 divide both sides by 2

    x = 71

    m∠1 = x - 33 → m∠1 = 71 - 33 = 38

    m∠2 = x + 71 → m∠2 = 71 + 71 = 142

    Answer: m∠1 = 38° and m∠2 = 142°
