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°
