Examine parallelogram abcd. angles a and d have measures of x and (x+30), respectively.
What is the value of x? Do not include the degree symbol.
Answered by oobleck
adjacent angles are supplementary - they add to 180°

Okay, I get that is is 75, but how did you get there?
Answered by Kaden
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...
