lets add all
3+5+9+13=28
so,
by taking first
we know that the sum of all angle og quadrilateral is 360
so =3 ÷28. × 360
this method would give your answer

let the angles in ratio be x
3x+5x+9x+13x=360°
8x+22x=360°
30x=360°
x=360/30
x=12
3x=12×3=36°
8x=12×8=96°
9x=12×9=108°
13x=12×13=156°
3x+5x+9x+13x=360°
8x+22x=360°
30x=360°
x=360/30
x=12
3x=12×3=36°
8x=12×8=96°
9x=12×9=108°
13x=12×13=156°
