1st angle=x
2nd angle=x+10
3rd angle=x+20
4th angle=x+30
so angles
1st angle+2nd angle+3rd angle+4th angle=360
x+x+10+x+20+x+30=360
4x+60=360
4x=360-60
4x=300
x=75
so
1st angle=x=75
2nd angle=x+10=75+10=85
3rd angle=x+20=75+20=95
4th angle=x+30=75+30=105
2nd angle=x+10
3rd angle=x+20
4th angle=x+30
so angles
1st angle+2nd angle+3rd angle+4th angle=360
x+x+10+x+20+x+30=360
4x+60=360
4x=360-60
4x=300
x=75
so
1st angle=x=75
2nd angle=x+10=75+10=85
3rd angle=x+20=75+20=95
4th angle=x+30=75+30=105
