Question

1. The angles of quadrilateral are in the ratio 3:5:9:13. Find all the angles of the
quadrilateral
barallelogram are equal then show that it is rectangle​

Answer 1

Answer:

first angle 36 sec. angle 60 third angle. 108 fourth angle 156

Step-by-step explanation:

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

since sum of all angles of quadrilateral is 360

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

=> 30x = 360

=> x = 12

so 12×3 =36 ,12×5=60 ,12×9=108 ,12×13=156
