Answer:
3:5:7 also remains same when x is multiplied x is common multiple in the nos.
135°+3x°+5x°+7x°=360°
135°+15x°=360°
225°/15°=x°
x°=15°
so the angles are 135°, 45°, 75°, 105°

Sum of interior angles if quadrilateral = 360
one angle = 135
360-135 = 225° ( Remaining measure)
Now, 3x + 5x + 7x = 225
15x = 225
x = 225/15 = 15°
All angles of a quadrilateral :
135°
3x = 45°
5x = 75°
7x = 105°
