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

The reflexive property of congruence lets you say that ∠pqr ≅

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
