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
/_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

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