Iven a circle with measures of (c, d, and r) and a circle with measures of (c', d', and r'), find r' if
c
c'
= 0.25 and d = 6.0.i

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
