The length of line segment BC is 18 units.
In triangle ABC, AB = 2x,
AC = 3x-7, and BC = 4x-10.
To find the length of line segment BC, we substitute the given values into the equation and solve for x.
BC = 4x-10
BC= 4(7)-10
BC = 28-10
BC= 18.
Therefore, the length of line segment BC is 18 units.
The probable question may be:
In triangle ABC , AB=2x, AC=3x-7, BC=4x-10
