Question

The four angles of a quadrilateral are in the 2:3:6:9.Find all the angles​

Answer 1

Answer:

36°, 54°, 108° and 162°

Step-by-step explanation:

The sum of angles of a quadrilateral = 360.

let the angles be 2x,3x,6x and 9x.

∴2x+3x+6x+9x =360 ⇒20x =360;  x = 18°

The angles are 36°, 54°, 108° and 162°

Answer 2

Answer:

let the angles be 2x,3x,6x,9x.

2x + 3x + 6x + 9x = 360

20 x = 360

x =360/20

× = 18
