Question

the angles of quadrilateral are the ratio 3:5:9:13 find all the angle of the quadrilateral.​

Answer 1

3x+5x+9x+13x=360

30x =360

x= 360/30

x=12

Answer 2

let the 1st angle be - 3 x

2nd be - 5x

3rd - 9x

4th- 13 x

acc. to the angle sum property of quadrilateral -

3x + 5x +9x + 13x = 360

8x + 9x + 13x = 360

30x = 360

x = 360/30

x = 12

3x = (3)(12)= 36

5x = (5)(12) = 60

9x = (9)(12) = 108

13x = (13)(12)= 156
