Answer: segment BC = 36 units
Step-by-step explanation:
As per the given information, we have
B, C and D are three points such that
segment BC = segment BD + segment DC ... (i)
And segment BD = segment DC ... (ii)
If segment BD = 18 units
Then, segment DC = 18 units [From (ii)]
segment BC = 18 units + 18 units [From (i)]
⇒segment BC = 36 units
Hence, length of [tex]\overline{BC}[/tex] = 36 units
