Which of the following is equal to the expression listed below? 11 x 5 +9 a . 9 x 11 + 5 b . 5 x 9 + 11 c . 5 x 11 + 9 d . 11 x 9 + 5

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
