Question

find the values of unknown x and y in the following diagram​

Answer 1

Step-by-step explanation:

(i) y = 180 -120

= 60

x=180-50-60

= 70

ii) y = 80

x =180 -80 -50

= 50

iii) y =180-50-60

= 70

x= 180-70

= 110

Answer 2

Answer:

(1) y+120=180 ( linear pair)

y=60

50+x+y= 180 ( angle sum property)

x = 70

(2) y=80 (vertically opposite angle)

50+x+y=180 (angle sum property)

x= 50

(3) y+50+60=180 ( angle sum property)

y=70

y+x=180 (linear pair)

x = 110
