Answer 2

60 degree

Step-by-step explanation:

angleACD + angleACB = 180 degree ( straight line angel)

angle ACD = 180degree - 120degree

so, angle ACB = 60 degree.

angle y = angle ACB= 60 degree ( issoscalen triangle properties)

Now,

angle x + angle y = 120degree (external angle properties)

Therefor,

angle X = 120degree - angle y

angle X = 60 degree
