Final answer:
The length of the line segment is 26.4 units.
Step-by-step explanation:
To find the length of a line segment with given endpoints, we can use the distance formula. The distance between two points (x1, y1) and (x2, y2) is given by:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the endpoints are (10.8, -5.3) and (-15.6, -5.3). Plugging these values into the distance formula:
Distance = sqrt((-15.6 - 10.8)^2 + (-5.3 - -5.3)^2)
Distance = sqrt(-26.4^2 + 0^2)
Distance = sqrt(26.4^2)
Distance = 26.4
Therefore, the length of the line segment is 26.4 units.
