Question

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

Answer 1

Answer:

angle 1 is 18 and 2 is 30 and 3 is 54 and 4 is 78

sum of all angles are 180°

let x,

3x+5x+9x+13x=180°

30x= 180°

x=180/30

x=6

now,

3(6) 5(6) 9(6) 13(6)

18° =30° =54° =78°
