Someone plz because i am using my last amount of points and i don't want it to be wasted from no answer. i need with questions 33,34,and 35. fast will give brainliest answer.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
