Which statement regarding the diagram is true?
mZWXY = m ZYXZ
m 2WXY mZWXY + m ZYXZ = 180°
mZWXY + m ZXYZ = 180°

How many different ways can you make change for $.50 using only nickels,dimes, and quarters?

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
