Question

The adjacent angles of a parallelogram are x degrees and (2x+30)degrees find all the angles of the parallelogram ​

Answer 1

Answer:

x + x+30 = 180 degree (angle sum property as well as properties of parallelogram )

2x + 30 = 180

2x = 180 - 30 =150

x = 150/2

x = 75 degree

x + 30 = 105 degree

therefore the adjacent angles are 75 degrees ,105 degrees......
