Answer:
5
Step-by-step explanation:
We are given that there are two line segments, red and blue, that stretch from the center of the circle to a point on the circle.
Given that the length of the blue segment is 5, we are to determine the length of the red segment.
Since both the line segments stretch from the center of the circle to its circumference so they must be equal.
Therefore, length of the red line segment is 5.
