K
The angles of a quadrilateral are in the ratio 1:1:3:7. Find each angle of the quadrilateral​

Answer 1

Step-by-step explanation:

let the common ratio of angles be x

so first angle is x

second angle is x

third angle is 3x

fourth angle is 7x

x+x+3x+7x= 360

12x =360

x= 360÷12

x=30

first angle is 30

second angle is 30

third angle is 90

fourth angle is 210
