Diagrams a and b are scale drawings of the same field. each square is 1 cm long if the scale of diagram a is 1 cm to 24ft what si the scale of diagram b.

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
