Question

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

Answer 1

Step-by-step explanation:

let the angles be

3x , 5x , 9x , 13x

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

30x = 360

x = 12

Angles

3x = 36°

5x = 60°

9x = 108°

13x = 156°

Answer 2

Answer:

Let the ratio be x

So, the angles are 3x, 5x, 9x and 13x

We know that,

Sum of all angles of a quadrilateral= 360°

Now,

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

30x=360

x=360/30

x=12

Therefore,

first angle=3x

=3*12=>36°

Second angle=5x

=5*12=>60°

Third angle=9x

=9*12=>108°

Fourth angle=13x

=13*12=>156°
