1.)If QR=12 and TS=15, then XY=_ 
2.)If QR =5 and TS=7, then XY=_ 
3.)If XY=24,then QR+TS=_ 
4.)If QR+TS=72, Then QR=_ 
5.)If XY=26 and TS=37, then QR=_ 
6.)If A is the midpoint of XT, B is the midpoint of YS, QR=14 and TS=20, then AB_ 
7.) If QT is congruent to RS and <SYX=160, find the measure of <R=? <Q=? <S=? 
8.)If Qt is counruent to RS and <TXY=145 find <S=? 
9.) If XT=1/2 RS and <T=20 find the m<R=? 

Plss help me thanks.
