∠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

∠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.
