Question

Please explain by a diagram or written​

Answer 1

Step-by-step explanation:

angle x= 70 degrees.       {vertically opposite angles are equal}

angle ACB = 180-130         {linear pair angles}

                  =50 degrees.

angle y= 180 degrees - angle x - angle ACB       {angles of a triangle}

           =180-70-50

           =60 degrees.

angle z=180 degrees - angle y      {linear pair angles}

           =180-60

           =120 degrees.

Hope it's clear ;)
