Answer 1

Step-by-step explanation:

i) x=90 degrees   (linear pair)

  z=150 degrees  (linear pair)

 

(180-y) + 90 +30=180   (sum of angles in triangle =180)

 therefore,  y=120 degrees

 x+y+z=90+120+150

          =360 degrees

ii) x= 60 degrees ((linear pair)

   y=100 degrees (linear pair)

   z=120 degrees (linear pair)

   (180-w)+120+80+60=360     (sum of angles in quadrilateral =360)

    therefore, w= 80 degrees

    x+y+z+w=60+100+120+80

                  =360 degrees
