Let the number be 3x:5x:9x:13x.
then,
= The measure of quadrilateral is 360°
So, 3x+5x+9x+13x =360°
30x = 360°
x = 360/30
x = 12°
then,
3x = 3×12 = 36°
5x = 5×12 = 60°
9x = 9×12 = 108°
13x = 13×12 = 156°.
The greatest angle is 156 °.
then,
= The measure of quadrilateral is 360°
So, 3x+5x+9x+13x =360°
30x = 360°
x = 360/30
x = 12°
then,
3x = 3×12 = 36°
5x = 5×12 = 60°
9x = 9×12 = 108°
13x = 13×12 = 156°.
The greatest angle is 156 °.
