LET THE ANGLES BE 2X,5X,9X,AND13X.
WE KNOW THAT SUM OF ALL THE ANGLES
OF QUADRILATERAL IS 360.
SO,2X+5X+9X+13X=360
29X=360
X=360/29
SO ,FIRST ANGLE=2×360/29=720/29
SECOND ANGLE=5×360/29=1800/29
THIRD ANGLE=9×360/29=3240/29
FORTH ANGLE=13×360/29=4680/29.
YOU CAN VERIFY IT BY ADDING ALL THE ANGLES IF SUM OF ALL ANGLES IS 360.
THEN YOUR ANSWER IS CORRECT.
