Is (52 + 2x0 supposed to be(52 + 2x) ?
Is (3x - 120 supposed to be (3x -12)
We can't come up with correct answers for you if the problems are typed wrong.
The sum of the two adjacent angles must be 180 degrees.
Use that fact to solve for x.
Then compute the angles.
If I guessed your errors correctly,
5x = 140 and x = 28.
That would make the angles 72 and 108 degrees.
the adjacent angles of a parallelogram are (3x-120 and (52+2x0.find the angles of the parallelogram?
