An angles measure is 6 degrees more than 3 times its compliment. find the measure of the angle.

a math tutor told me to let the angle be 0
6 degrees + 30 = 90
-6 -6
30/3=84 degrees
0=28 degrees
then i check the back of my math book and it said the answer was 69 degrees

help?

let the smaller angle be x..then the larger one is 3x+6..then since they r complimentary...3x+6+x=90 meaning..x=21....so larger angle...the one u require is 3x+6 thats 3*21+6=69...
