Question

In a quadrilateral, the angles are xº, (x + 10), (x+20)°, (x+30). Find the angles​

Answer 1

Answer:

measure of all angles = 360

therefore

x+x+10+x+20+x+30=360

4x+ 60=360

4x=360-60

4x=300

X=300÷4

Step-by-step explanation:

x=75

1st angle =75

2nd angle =75+10=85

3rd angle =75+20=95

4th angle =75+30=105

Answer 2

Answer:

Given angles of the quadrilateral are x,x+10,x+20,x+30

Sum of angles in a quadrilateral is 360

therefore x+x+10+x+20+x+30=>360

=> 4x +60 = 360

=> 4x=360-60

4x=300

x=300/4=75

hence the angles of the quadrilateral are x = 75

x+10=75+10=85

x+20=75+20=95

x+30=75+30=105

hence the angles of the quadrilateral are 75,85,95 and 105
