Question

the angles of quadrilateral are in the ratio 3: 5: 9: 13. find all the angles of the quadrilateral. mcq answer me​

Answer 1

Answer:

36, 60, 108, 156

Explanation:

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 ∘ =36 ∘, 5×12 ∘ =60 ∘, 9×12 ∘ =108 ∘ and 13×12 ∘ =156 ∘
