Q4 of 95 Page 14

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

Given,


Ratio of angles of quadrilateral = 3:5:9:13


Let angles are = 3x, 5x, 9x, 13x


So,


3x+5x+9x+13x = 360∘


30x = 360∘



Angles would be =


3x = 3×12 = 36


5x = 5×12 = 60∘


9x = 9×12 = 108∘


13x = 13×12 = 156∘
