can we construct a line perpendicular to AB and CD then the sum of angle A+ angle B + angle D + angle C + angle E (angle x)
=≥ 120°+90°+90°+125°+x = 540°
=≥ 425+x=540°
=≥ x=540°-425°
=115°
_*IS THERE ANY OTHER WAY ?????????*_

Yes you can draw a line through E so that
Construction: MN through E so, MN || AB || CD
Now,
1/2(x) = 180-120 ( co interior)
1/2(x)’= 180-125 (co interior)
1/2(x)+ 1/2(x)’= x
60+55= x
115= x
Hope it helps :)
