The angles of the quadrilateral are in the ratio 4 : 5 : 10 : 11. The angles are given below:

Concept use:

The Sum of Angles of Quadrilateral = 360° 

Calculation:

The angles of the quadrilateral are in the ratio 4 : 5 : 10 : 11. 

∴ 4x + 5x + 10x + 11x = 360° 

⇒ 30x = 360° ⇒ x = 12° 

Hence, The Angles of Quadrilaterals are 48°, 60°, 120°, 132° 

Hence, The Correct Answer is 48°, 60°, 120°, 132°.
