Hey mate
The greatest angle is of 135 degree
I hope it helps you
plz mark me as brainliest and follow me.....
Answer:
ratio. = 3:5:7:9
let it be 3x + 5x+ 7x + 9x = 360
(. sum of all angles of quadrilateral is 360 )
24x = 360
x = 360 / 24
x = 15
3x= 3×15= 45
5x= 5×15=75
7x=7×15=105
9x= 9×15=135
so the greatest angles of quadrilateral is 135.....
