Question

i want ans 3 ,4 and 5

Answer 1

let's the four angles in the ratio 3 x 5 x 9 x and 13 x
3 x +5 x +9 x +13 x=360 (angle sum property of quadrilateral)
30x=360
x=12
the four angles of quadrilateral 36 degree 60 degree 100 degree and 156 degrees

Answer 2

question no.4
let the sides be=x
therefore,
sides are 3x,5x,9x and 13x
the sum of all sides of quadrilateral is= 360

3x+5x+9x+13x=360
30x=360
x=12

substituting the value of x
3x=12×3=36
5x=5×12=60
9x=12×9=108
13x=13×12=156
therefore the angles are 36,60,108 and 156
