The angles of a quadrilateral are in the
ratio 3:5:9
3:5:9:13 Find all the angles, of a
quadrilateral​

Answer 1

Step-by-step explanation:

suppose,the angles of quadrilateral is

3x:5x:9x:13x

3x+5x+9x+13x=360°

30x=360°

x=360°/30

x=12°

therefore,

angles of quadrilateral is,

3x=3*12=36°

5x=5*12=60°

9x=9*12=108°

13x=13*12=156°
