Question

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

Answer 1

Answer:

Let the four angles of the quadrilateral be 3x, 5x, 9x and 13x

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

∘

[sum of all angles of the quadrilateral is 360

∘

]

30x=360

∘

x=12

∘

Hence, the angles of the quadrilateral are 3×12
