Which expression is equal to 1/36? a 1/3 x 1/6 b 1/4 x (1/3)^2 c (1/2)^2 x (1/3) ^2 d 1/2 x 1/3 x 1/3 x 1/3

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
