Question

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

Answer 1

Answer:

let the angle of quadrilateral be x

so 3x,5x,9x,13x

Step-by-step explanation:

$3x+5x+9x+13x =360\\30x=360\\x=12$

Answer 2

Answer:

suppose;

3=3x

5=5x

9=9x

13=13x

then the x= 12

Step-by-step explanation:

3x+5x+9x+13x=360°

30x=360°

x=360°/30

x=12

then ,3x=3×12=36°,

5x=5×12=60°,

9x=9×12=108°,

13x=13×12=156° .
