iii)  y+50+60= 180
   =>y= 70
and x+y= 180
=> x= 110
iv) 70 = x vertically opp
70+30+y= 180
=> y = 80

=> x= 110

Answer 2

Hello friend
----------------------------------------------------------------------------------------------------
1) y + 50° + 60° = 180° ( A.S.P)
= y + 110° = 180°
= y = 70°
Now,
         x + y = 180° ( L.P.A)
      = x + 70 = 180°
      = x = 110°
.......................................................................................................................
2) x + y + 30° = 180° (A.S.P)
=  70° + y + 30° = 180° ( x = 70 as V.O.A)
=  y + 100° = 180°
=  y = 80°
So, x = 70° and y = 80°
