Question

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

Answer 1

Answer:

ratio of angles =3:5:9:13

let first angle =3x

let second angle =5x

let third angle =9x

let fourth angle =13x

by angle sum property

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

30x=360

x=360/30

x=12

first angle =12*3=36

second angle =12*5=60

third angle =12*9=108

fourth angle =12*13=156
