Question

the angle of a quadrilateral are 7x, 10x, 11x and 12x. find the value of x and all the angles of the quadrilateral ​

Answer 1

Answer:

7x+10x+11x+12x=360(sum of all angle of quadrilateral)

40x=360

x=9

1angle=9×7=63

2angle=9×10=90

3angle=9×11=99

4angle=9×12=108

Answer 2

Answer:

value of x is 9

Step-by-step explanation:

sum of angles of quadrilateral is 360

Therefore,7x+10x+11x+12x=360

40x=360

x=360/40

x=9

and all the angles are

7×9=63

10×9=90

11×9=99

12×9=108
