Question

60° 80° W 120° x (b) Find x + y + z + w​

Answer 1

Step-by-step explanation:

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°
