Question

in a quadrilateral the angles are in x degree x+10degree,x+20degree,x+30degree find
angles​

Answer 1

Answer:

75,85,95,105

Step-by-step explanation:

x+x+10+x+20+x+30=360°

4x +60=360°

4x=360-60

4x=300

x=300/4

x=75

•°•x=75

x+10=75+20=85

x+20=75+20=95

x+30=75+30=105

Answer 2

x+(x+10)+(x+20)+(x+30)=360 degree (Angle sum property
4x+60=360
4x=360-60=300
4x=300
x=300/4
x=75
1st angle=75
2nd angle=75+10=85
3rd angle =75+20=95
4th angle=75+30=105
