Question

pls answer this carefully ​

Answer 1

Answer:

Let the angles be x,3x,5x,9x

according to the problem

x+3x+5x+9x=360°

18x=360°

x=20°

Here u get the smallest angle

Answer 2

Answer:

smallest angle =20

Step-by-step explanation:

...

let angle = x

angle 1 =1x............(1)

angle 2. =3x......(2)

angle 3. =5x.......(3)

angle4 =9x......(5)

in quadrilateral addition of all angle equal to 360.

(angle 1 )+ (angle 2)+ (angle 3 )+ (angle 4)= 360

1x+3x+5x+9x =360

18x = 360

x= 20....

mark me brilliant.plz..
