Question

Point Key was on a line segment PR. Given PQ=5 and QR=8, determine the length of PR.

A) 13 units
B) 3 units
C) 40 units
D) 2 units

Answer 1

The length of line segment PR is the sum of the lengths of PQ and QR, which equals 5 units + 8 units = 13 units.

Step-by-step explanation:

The question asks for the length of the line segment PR, given that point Q is between P and R, and the lengths of PQ and QR are 5 units and 8 units, respectively. Since line segments PQ and QR are contiguous and part of the same straight line, the total length of PR is the sum of PQ and QR. Therefore, to find the length of PR, you simply add the length of PQ to the length of QR:

PQ + QR = PR

5 units + 8 units = 13 units

Thus, the length of line segment PR is 13 units.
