90 divided by 9 is 10 so you can subtract 9 from 90 for 10 times before you reach 0 if you want to go into negative numbers you can keep subtracting as many times as you like you are sooooooooo wrong WOW. You can subtract 9 once from 90 because once you subtract 9 from 90, 90 becomes 81. That's how I do it
0 and 90 1 and 89 2 and 88 0.5 and 89.5 etc. Just choose any number for the first angle, and subtract it from 90 to get the second angle.
No, it is not.
complementary angles add to 90 degrees subtract from 90 90-35 = 55
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement

180 - 90 is 90
if you subtract 0 from 5 is still 5. but if you subtract 5 from 0 then it would be -5.
