Answer:
The length of QS and TV is 8 units
Explanation:
we know that
If triangle QRS is congruent with triangle TUV
then
QS=TV
QR=TU
RS=UV
In this problem
we have
QS=3v+2
TV=7v-6
so
QS=TV
3v+2=7v-6
Solve for v
7v-3v=2+6
4v=8
v=2
Find the length of QS
substitute the value of v
QS=3(2)+2=8 units
so
TS=8 units
