Question

The angle A,B,CandD of a quadrilateral ABCD are in the ratio 1:3:7:9?

plz answer me​

Answer 1

Answer:

Step-by-step explanation:

let they be x,3x,7x,9x

then,

x + 3x + 7x + 9x = 360 (sum of angles of a quadrilateral)

=> 20x = 360

=> x = 18 degrees

Answer 2

Step-by-step explanation:

let the angle be x

so ,x ,3x,7x,9x

and ,

x+3x+7x+9x=360 (sum of angles of quadrilateral )

20x=360

x=18

so A=18

B=54

C=126

D=162
