Question

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

​

Answer 1

Answer:

Sum of all angles of a Quadrilateral=360°

Let the common ratio of the angles be x

Therefore, 3x+5x+9x+13x=360°

30x=360°

x=360÷30

x=12

So, 3x= 3×12=36°

5x= 5 × 12=60°

9x=9×12=108°

13x=13×12=156°

Answer 2

Answer:

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

30 x =360

X = 360/ 30

X =12.

Now We Put 12 In The Place of X.

5(12) = 60.

9(12) = 108.

13 (12)=156.

3 (12) = 36.
