adjacent angles are supplementary - they add to 180°
For future viewers, the answer for this is 75.
anna is correct.
Okay, I get that is is 75, but how did you get there?
Okay I figured it out.. Angle A + angle D = 180 degrees because it is supplementary..
X = 75
75 + 30 = 105 (which is angle D)
75 (angle A)
105 + 75 = 180 degrees (A + D =180), so it is correct...
X = 75
75 + 30 = 105 (which is angle D)
75 (angle A)
105 + 75 = 180 degrees (A + D =180), so it is correct...
