2 angles are supplementary an have measures angle 1 = (x + 40) and angle 2 = x what is the measure of angle 1?
Since the angles are supplementary, we know that their measures add up to 180 degrees.
angle 1 + angle 2 = 180
(x + 40) + x = 180
2x + 40 = 180
2x = 140
x = 70
Therefore, the measure of angle 1 is:
angle 1 = x + 40
angle 1 = 70 + 40
angle 1 = 110
