Let the angles of quadrilateral be 3:5:9:13=3x,5x,9x and 13x.
3x+5x+9x+13x=360° (Angle sum property of Quadrilateral)
or, 30x=360°
or, x=360/30
or, x=12
3x=3X12=36°
5x=5X12=60°
9x=9X12=108°
13x=13X12=156°
Hence, Angles of Quadrilateral are 36°,60°,108°,156°
3x+5x+9x+13x=360° (Angle sum property of Quadrilateral)
or, 30x=360°
or, x=360/30
or, x=12
3x=3X12=36°
5x=5X12=60°
9x=9X12=108°
13x=13X12=156°
Hence, Angles of Quadrilateral are 36°,60°,108°,156°

Answer:
36 60 108 156
Step-by-step explanation:
let the ratios be x
3x 5x 9x 13x
3x plus 5x plus 9x plus 13x=360
30x=360
x=12
3x=36 5x=60 9x=108 13x=156
