Abbeys cat weighs 18 pounds. her dog weighs 2 pounds more than half her cats weight. write and evaluate an expression to show how much abbeys dog weighs

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
