draw a line through E ll to ab mark R now,
angle BGE + GER = 180° (co interior angls)
= 135 +ger = 180
= ger = 180-135
=45°
now, angle DFE+FER= 180°
=FER = 180°-125°
= 55°
we have x=FER+GER
= x= 100°
angle BGE + GER = 180° (co interior angls)
= 135 +ger = 180
= ger = 180-135
=45°
now, angle DFE+FER= 180°
