Question

Q23.The angles of a quadrilateral are in the ratio 3:5:9:13. Find
all the angles of the quadrilateral.​

Answer 1

Step-by-step explanation:

let ratio be x

so now angles are :-3x,5x,9x,13x

sum of all angles in quadrilateral are 360

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

30x=360

x=360/30

x=12

now

angles are:- 3x=3×12=36

5x=5×12=60

9x=9×12=108

13x=13×12=156

Answer 2

Answer:

3x+5x+9x+13x=360⁰

30x=360⁰

X=360⁰/30

X=12

3x=12×3=36

5x=12×5=60

12 x=12×13=156

the angle of the quadrilateral = 12,36, 60 , 156
