Step-by-step explanation:
I don't know if this helps, but none of the above.
first of all, complementary angles mean that the 2 (or more) angles add up to 90 degrees. so, if you were to combine the angles, you'll get an angle that's way larger than 90 degrees. (a and b won't work cause 830 isn't an angle)
P.S. but 83 degrees and 7 degrees would be complementary...
hope you at least know why i say none of the above
