Question

in the figure below, ( pq = 18 ) and ( pr = 33 ). find ( qr ).

Explanation:

Step1: Use the segment addition postulate

From the figure, we know that \(PR = PQ+QR\).

Step2: Solve for \(QR\)

Rearrange the formula to \(QR=PR - PQ\). Substitute \(PQ = 18\) and \(PR = 33\) into the formula: \(QR=33 - 18\).
Calculate \(33-18\): \(QR = 15\).

Answer:

\(15\)
