Question

Plzz..... Could anyone solve this

Answer 1

hey here is ur solution :-----

given :-AB||CD||EF
so, <ABG+<EGB=180 [by co-int.angle]
110+<EGB=180
<EGB=180-110
<EGB=70

and, similarly

<DCG+<FGC=180
100+<FGC=180
<FGC=180-100
<FGC=80

now,
<EGB+<BGC+<FGC=180. [by LP]
70+80+<BGC=180
150+<BGC=180
<BGC=180-150
<BGC=30

HOPE THIS HELP U.....
