sum of all angles in a parallelogrm= A+B+C+D
360=2 (3x-10)+2 (5x+30)
360=6x-20+10x+60
360=16x+40
360-40=16x
320=16x
x=20
A is 50 degree and B is 130 degree alsoC is 50 degreee and D is 130
360=2 (3x-10)+2 (5x+30)
360=6x-20+10x+60
360=16x+40
360-40=16x
320=16x
x=20
A is 50 degree and B is 130 degree alsoC is 50 degreee and D is 130
