as we know sum of all sides of a quadrilateral is 360 degree
so 2x+3x+7x+8x =360by solving x =18 degree
so 7x+3x =180 so as we know the sum of interior angles of the angles formed by the transversal is 180 thus the opposite sides are parallel
so 2x+3x+7x+8x =360by solving x =18 degree
so 7x+3x =180 so as we know the sum of interior angles of the angles formed by the transversal is 180 thus the opposite sides are parallel

thanks but what do you mean by interior andle is a quadrilateral and there is no diagonals
have you studied transversal line???
yeah
the opposite side are parallel as the adjacent side is acting as transversal
and the sum of interior angles formed by the transversal on the same side is 180
have u got
yeah yeah i got it and once again thanks for helping me
wclm
Mark as brain list please
ok

sum of a quadrilateral = 360 degree
2x +3x+ 7x + 8x = 360
20x = 360
x= 18
2x = 36
3x = 54
7x = 126
8x = 144
opposite sides are ll as it is a rombus
2x +3x+ 7x + 8x = 360
20x = 360
x= 18
2x = 36
3x = 54
7x = 126
8x = 144
opposite sides are ll as it is a rombus
how please elaborate
