in a parallelogram:
opposite sides are parallel
opposite sides are equal in length
opposite angles are equal
the sum of all angles in a parallelogram is 360

so,if one angle is x and its adjacent angle 2x, then

x+%2B+x+%2B+2x+%2B+2x+=+360+
6x+=+360+
x+=+360%2F6+
highlight%28x+=+60+%29
and its adjacent angle highlight%282x=120%29
