Answer :
Let's solve this, following the hint that was provided: Given that line segment QS = 54.4 and line segment RS = 39.3.
we are also told that line segment QR is part of line QS, which is equal to line QR + line RS.
So to find line segment QR, we need to subtract the length of line segment RS from that of QS, i.e., QR = QS - RS
Substituting the given values into the equation,
We get QR = 54.4 - 39.3
When this subtraction is performed, it gives us the length of line segment QR as approximately 15.1.
