In a parallelogram , one angle is 45th of its adjacent angle. Then the angles of the parallelogram are
100, 80
Let x and y be the adjacent angles of the parallelogram.
Then, x+y=180 ...(1)
And, x=45y
5x=4y⇒5x−4y=0 ...(2)
Multiplying (1) by 4,
4x+4y=720 ...(3)
Adding (2) and (3),
9x=720⇒x=80
∴y=180−80=100
Therefore, the angles are 1000,800.
