Answer 1

Answer:

ok I do it

Step-by-step explanation:

3:5:7:9

3x+5x+7x+9x =720

24x=720

x= 720/24

x=30

so the angles of quadrilateral

3×30=90

5×30=150

7×30=210

9×30=270

Hope it's help full for u

Answer 2

Answer:

you know that sum of all angles of quadrilateral is 360°

let angle be 3x , 5x ,7x and 9x

sum of all angles of quadrilateral = 360°

3x+5x +7x+ 9x =360°

24x =360°

x=360/24

x=15°

3x= 3x15° = 45°

5x= 5 x 15°=60°

7x= 7 x15°= 105°

9x = 9x 15°=135 °
