Answer:
let common ratio is=x
as sum of angle of qyadrilateral is 360
- 2x+3x+4x+4=360
- 9x=360-4
- 9x=356
- x=356/9
- x=35.6

Answer:
Sum of all angles of a quadrilateral is 360
Let the measure of the angles be: 2x , 3x, 4x , 45 ( as given )
So , 2x + 3x + 4x + 45 = 360
9x + 45 = 360
9x = 360 - 45
x = 315 / 9 = 35
The measures of the angles of the quadrilateral is:
45 , 70 , 105 , 140
