1st we will find x
x=180-120
x=60 (linear pair)
2nd we will find y
y=180-80
y=100
3rd we will find z
z=180-60
z=120
now, w is left and we know that sum of all the interior angles of a quadrilateral is 360 so
60+120+80=260
so the 4th angle inside the quadrilateral will be 100
and the value of w will be
w=180-100
w=80
now sum of w,x,y,z will be
=80+60+100+120
=360
x=180-120
x=60 (linear pair)
