Answer 1

Answer: segment BC = 36 units

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
`\overline{BC}` = 36 units
