Question

in the figure below, ( pq = 8 ) and ( qr = 7 ). find ( pr ).

Explanation:

Step1: Apply the segment addition postulate

The segment addition postulate states that if \(Q\) is a point on the line segment \(PR\), then \(PR = PQ+QR\).
Given \(PQ = 8\) and \(QR = 7\).

Step2: Substitute the values

Substitute the values of \(PQ\) and \(QR\) into the formula \(PR=PQ + QR\).
So, \(PR=8 + 7\).

Step3: Calculate the sum

\(8+7=15\).

Answer:

\(15\)
