Koi to answer de do...​

Answer 1

${\huge{\boxed{\mathbb{ANSWER}}}}$

I think ur ques is incomplete ,

it should be

3:5:9:13

Let the ratios be 3x , 5x , 9x ,13x

Now ,

As , we know that ,

the sum of internal angles of a Quadrilateral = 360°

3x + 5x + 9x + 13x = 360°

30x = 360°

x = 12°

Now ,

put the value of x in the ratios

1st Angle = 3x = 3×12 = 36°

2nd Angle = 5x = 5×12 = 60°

3rd Angle = 9x = 9×12 = 108°

4th Angle = 13x = 13×12 = 156°
