Question 345376
let measure of G be x
complement will be 90-x
supplement of complement will be 180-(90-x)
=90+x
....
ratio = (90-x)/(90+x)= 1/4 
4(90-x)=90+x
360-4x=90+x
add 4x
360-4x+4x=90+x+4x
360=90+5x
add -90
360-90==5x
270=5x
divide by 5
54 = x   measure of G
supplement of G = 180-54 = 126
Ratio = 54/126
=3/7
