what are the instructions for 14 and 15?
17 and 18 are incomplete. you found the complimentary angle, you must find the supplementary one also
40, 69, 71 and 72 are incorrect
the rest are fine (except, possibly, 14 and 15, i don't know what you're supposed to be doing on those)
for help with 69, 71, 72, see here, there is even a calculator at the bottom where you can check your answers
