Question

(d)
60°
80°
120°
(b) Find x + y +z+w​

Answer 1

120+x=180 ....by linear pair

x=180-120

x=60°

80+y=180 ....by linear pair

y=180-80

y=100°

z+60=180 ....by linear pair

z=180-60

z=120°

4th angle of figure = 360-(120+80+60).by angle sum property

=360-260 =100°

4th angle+ w=180 ....by linear pair

w=180-100

w=80°

x+y+z+w = 60+100+120+100

======>380°

Answer 2

Answer:

×=60.

y=100'

z=120'

w=
