question
point q is on line segment \\(\overline{pr}\\). given \\(pq = 12\\) and \\(qr = 3\\), determine the length \\(\overline{pr}\\).
answer attempt 2 out of 2
\\(pr = \\) text box with 11 submit answer

Explanation:

Step1: Recall segment addition postulate

If Q is on segment \( \overline{PR} \), then \( PR = PQ + QR \).

Step2: Substitute given values

Given \( PQ = 12 \) and \( QR = 3 \), so \( PR = 12 + 3 \).

Step3: Calculate the sum

\( 12 + 3 = 15 \).

Answer:

15
