Question 1069263: The difference between 2 adjacent angles of parallelogram is 20 degrees.find measures of all angles
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
Adjacent angles are supplementary.
x is one angle
x-20 is the other
they add to 180 degrees
2x-20=180
2x=200
x=100 degrees: two corners on opposite sides are 100 degrees
x-10=80 degrees: the other two corners
