ohk batata hun bhai
join ac
now since AB || CD , so angle BAC + angle DCA = 180 .
so, 50+ angle CAE + 70 + angle ECA = 180
So, angle EAC + angle ECA = 60
Now in triangle ACE , 60 + angle AEC = 180
so angke ACE = 120°
sorry it is angle galti se angke type ho gya
welcome bhai

value of x° is (50°+70°) = 120°
what??
draw a parallel line with AB on E
kuch dikha..

first of all join AC and BD
then it will be a rectangle
and AEC will be a triangle
then angle B=90 and D=90
all angles of rectangle are 90
then
a=A-50=90-50=40
c=C-70=90-70=20
from triangle AEC
as sum of all angles of triangle is 180
then
angle a+c+x=40+20+x =180
x=180-60=120
therefore angle x=120
then it will be a rectangle
and AEC will be a triangle
then angle B=90 and D=90
all angles of rectangle are 90
then
a=A-50=90-50=40
c=C-70=90-70=20
from triangle AEC
as sum of all angles of triangle is 180
then
angle a+c+x=40+20+x =180
x=180-60=120
therefore angle x=120
