Step-by-step explanation:

1) angle BCD = 180° --------( straight angle )

angle acd = 123°

angle acb = ?

therefore acb+ acd = BCD

therefore acb+ 123 = 180

therefore acb = 180-123

therefore acb = 57°

in triangle ABC ,

angle a + angle b + angle c = 180° -------( sum of all angle of triangle is 180°)

therefore 56+b+57= 180°

therefore b= 180 - 113

therefore b= 67°

therefore X= 67°

3) angle a + angle b + angle c = 180°------( sum of all angle of triangle is 180° )

therefore 25° + X + 30° = 180°

therefore x= 180-55

therefore X = 125°
