Answer:
BC = 144 units
Step-by-step explanation:
It is given a line segment BC.
D is the point on the line segment.
To find the length of BC
BC = 8x
CD = 3x + 8 and BD = 4x + 10
BC = CD + BD
8x = 3x + 8 + 4x + 10
8x = 7x + 18
x = 18
BC = 8x = 8 * 18 = 144 units
Therefore the length of segment BC = 144 units
