Question

The angles o quadrilateral que ün #the
ratio 3:5:9:13. Find all the angles
el quadrilateral​

Answer 1

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

3x+5x+9x+13x

And we know that the sum of the angles of a quadrilateral is 360°

Therefore,

3x+5x+9x+13x=360°

30x=360°

x= 360÷30

x=12

Therefore,

the angles are 12×3=36°, 12×5=60°, 12×9=108°,13×12=156°
