Step-by-step explanation:Just think about it

13

Step-by-step explanation:

This is a Pythagorean Theorem question. Line PR's length is 12, and line PQ's length is 5.

12^{2} + 5^{2} is 144 + 25 = 169

= $13$

the square root of what number? if you add that, then someone will probably answer the question.
