Let the angles be 3x, 4x and 5x.
=> 3x + 4x + 5x + 108 = 360°
=> 12x = 252°
=> x = 21°
=> 3x = 63°
=> 4x = 84°
=> 5x = 105°
=> 3x + 4x + 5x + 108 = 360°
=> 12x = 252°
=> x = 21°
=> 3x = 63°
=> 4x = 84°
=> 5x = 105°

All angles in a quadrilater iz 360.
One of the angle iz 108
Sum of remaining angles iz 360-108=252
3x+4x+5x=252
12x=252
x=252/12
x=21
3(21)=63
4(21)=84
5(21)=105
