Question

1. The angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. Find all the angles of the quadrilateral.

​

Answer 1

Answer:36,60,108,156

Step-by-step explanation:

let angles 3x,5x,9x,13

3x+5x+9x+13x=360 (sum of all angles of quadrilateral)

30x=360

x=12

12*3= 36

12*5=60

12*9=108

12*13=156

plz follow me !!!!!

Answer 2

Step-by-step explanation:

let the angles of a quadrilateral be= 3x, 5x, 9x, 13x ..

Sum of all angles = 360°

= 3x + 5x + 9x + 13x = 360°

= 8x + 22x = 360°

= 30x = 360°

= x = 360 ÷ 30

= x = 10 ANS......
