answer Who is the Math king

Answer 1

10) answer

let us take the angles to be :

3k , 5k , 9k , 13k

the total angle of a quadrilateral is 360 degree

SO :

3k + 5k + 9k + 13k = 360

30 k = 360

k = 360/30 = 120/10 = 12

therefore the angles are : 3* 12 , 5* 12 , 9*12 , 13* 12

ie : 36 , 60 , 108 , 156

therefore the greatest angle of the quadrilateral is 156 degrees.
