Question

∠1 and ∠2 are supplementary angles. m∠1 = x − 39, and m∠2 = x + 61. Find the measure of each angle.
∠1 = 79, ∠2 = 101
∠1 = 40, ∠2 = 150
∠1 = 40, ∠2 = 140
∠1 = 79, ∠2 = 111

    the third choice is correct.
    X-39 + x+61 = 180
    2x + 22 =180
    2x = 158
    X= 79
    then you plug into the angles:
    79 – 39 = 40 — angle 1
    79 + 61 = 140 — angle 2

    140 plus 40 is 180.
