Firstly value of y= /.ACD
=> /.ACD+/.CDA = /.EAD (exterior angle property)
=> y+50 = 120
=> y = 120-50
=> y = 70°
Now x= /.ACB (angles on the opposite side of equal sides are equal)
=> /.ACB+y =180° (linear pair)
=> /.ACB+70 =180
=> /.ACB=180- 70
=> /.ACB =110°
=> /.ACB = x therefor x = 110°
Hope it helped

thanks but in the answersheet the value of y is 110 and the value of x is 70
Same both
They would have taken opposite variables
