Answer 1

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 $\overline{BC}$ = 36 units
