let 3=3x
4=4x
5=5x
8=8x
3x+4x+5x+8x=20x
20x=180
x=180/20=9
3x=27 4x=36 5x=45 6x=54
4=4x
5=5x
8=8x
3x+4x+5x+8x=20x
20x=180
x=180/20=9
3x=27 4x=36 5x=45 6x=54

no sum of quadrilateral is 360 degrees
ya
sry
it will be 20x=360 x =18
hmmm

if the angle be = x
then 3x,5x,4x,8x = 360 ( since sum of quadrilatrals is 360 )
3x+5x+4x+8x=360
20x=360
x=360/20
x=18
then 3x18= 54
5x18= 90
4x18=102
8x18=144
then 3x,5x,4x,8x = 360 ( since sum of quadrilatrals is 360 )
3x+5x+4x+8x=360
20x=360
x=360/20
x=18
then 3x18= 54
5x18= 90
4x18=102
8x18=144
