Question

The opposite angle of a quadrilateral is supplementary to each other. If the difference between the pairs of opposite angles is 40° and 20°, Find the measure of the angles of the quadrilateral ​

Answer 1

Answer:

2x+2y =360

x+y=180

x-y=20

2x=200

x=100

100+y=180

y=80

x+y=180

x-y=40

2x=220

x=110

substitute x=110

110+y=180 y=70angles are 100,80,70,110
