since AB||CD so
/_1=/_2. (corresponding Angles)
3x+5=7x+5
3x=7x
4x=0
x=0
angle 1=3×0+5=5°
angle 2=7×0+5=5°

angle 3+angle 1=180. linear pair
angle 3=180-5=175°
angle 4=angle 3=175° corresponding angle

salma4488: answer is x =17°, /_1=56°, 2=124°3=124°,4=56°
chopraneetu: not possible dear as if lines are parallel then corresponding angles are equal
chopraneetu: angle 1 and angle 2 are correspondence angles so have to be equal
chopraneetu: the answer which you are saying will come if instead of angle 2 angle 3 will be of 7x+5
chopraneetu: then the same answer will come
chopraneetu: which you are saying
salma4488: itz
salma4488: its ok
chopraneetu: :)
