Answer 1

Opposite angles of parallelogram are equal .
There fore taking the ratio to be x proceed.......
5x+5x+4x+4x equals 360 degree ( sum of internal angles of a quadrilateral equal 360 degree)
18x equals 360 degree
x equals 20 degree
therefore angles r 5x equals 100 degree 4x equals 80 degree...........
