given,
x+y+40=180 (by angle sum property in triangle)
and x-y=30
now
x-y=30
x=30+y
put in other equation
x+y+40=180
30+y+y+40=180
2y=110
y=55
x=30+y
x=30+55
x=85
x+y+40=180 (by angle sum property in triangle)
and x-y=30
now
x-y=30
x=30+y
put in other equation
x+y+40=180
30+y+y+40=180
2y=110
y=55
x=30+y
x=30+55
x=85
