Ellie compared 4/7 and 5/3 by first comparing each fraction to 1/2 and 1.
step 1: 4/7 is less than 1 but more than 1/2
step 2: 5/3 is more than 1
step 3: so, 4/7 > 5/7
in which step did
ellie make her first mistake?

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
