Answer:
let the angles be 2x, 3x, 4x ,1x
Now,
We know that,
Sum of all angles of quadrilateral = 360°
2x+3x+4x+x = 360
10x = 360
x= 36
Now,
1st angle = 2x =2×36 = 72°
1st angle = 2x =2×36 = 72° 2nd angle = 3x = 3×36 = 108°
1st angle = 2x =2×36 = 72° 2nd angle = 3x = 3×36 = 108° 3rd angle = 4x = 4×36 = 144°
4th angle = x = 36°
