Angle d = angle b =105
a + c = 2x
360= 105 + 105 +2x
2x = 150
angle c = angle a = 75

I think the solution  is
angle d =  b angle
angle c = angle a
c+a =2x
so, if angle d = angle b then both are of same measures
so both = 105°
then 360° = 150°+150°+2x
2x = 150
as angle c = angle a so again both are of same measures
so both= 70°
