Yeah this is rlly old work I didn’t do anddd I don’t remember how to do any of it cs I’m so far ahead so help? The first person I’ll mark as brainliest

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