anonymous · Answer

$$how would I find the length for QR$$

anonymous · Answer

it depends....... what sre the numbers for Q and R??

anonymous · Answer

For u and v vectors, collinear means : u = k*v or v=k*u
which means if M and N are points, OM = k*ON +A or ON=k*OM + A where 1 is a point
And that means they are on the same line

anonymous · Answer

PT=20, QS=6, amd PQ=QR=RS; im just really confused on the concept of how to do it.
