CBSE Class 9 Answered

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

Asked by Topperlearning User | 16 Aug, 2017, 02:25: PM
Expert Answer

Let the angles be 3x, 5x, 9x, and 13x.

3x + 5x + 9x + 13x = 360o       (angle sum of a quadrilateral)
30x = 360o  x =12o
Hence, the angles are 36o, 60o, 108o and 156o.
