GIVEN:- ANGLES OF A QUAD. IN RATIO i.e 3:5:7:9
TO FIND :- ALL THE ANGLES
HERE WE START:-
LET EACH ANGLE =A= 3x ( to seperate from ratio multiply by any variable)
B= 5x
C= 7x
D= 9x
NOW USING ANGLE SUM PROPERTY OF A QUAD. :-
SUM OF ALL ANGLES = 360°
A+B+C+D=360°
=> 3x+5x+7x+9x=360°
=> 24x=360°
=> x=360/24
x= 15
Now put x= 15 in all the angles
A=3×15=45°
B=5×15=75°
C=7×15=105°
D=9×15=135°
