Let the angles be 3x, 5x, 4x & 3x.
All angles of a quadrilateral sum up to 360°
Hence we can write,
3x + 5x + 4x + 3x = 360°
15x = 360°
x = 360/15 = 24°
.·. 1st angle = (3×24) = 72°
2nd angle = (5×24) = 120°
3rd angle = (4×24) = 96°
4th angle = (3×24) = 72°
Now, verify if all the angles sum upto 360° or not.
(72+120+96+72)° = 360°
