Question

What is the length of BC¯¯¯¯¯ ?



Enter your answer in the box.

Answer 1

2x - 24 = x - 2
2x - x = 24 - 2
x = 22

BC = x = 22

Answer 2

Answer: The required length of BC is 22 units.

Step-by-step explanation: We are given to find the length of BC from the figure.

From the figure, we note that ABC is an isosceles triangle, with AC = AB, where

AC = 2x-24, AB = x-2 and BC = x.

Since AC = AB, so we get

`2x-24=x-2\\\\\Rightarrow 2x-x=24-2\\\\\Rightarrow x=22.`

Therefore, we get

BC = x = 22.

Thus, the required length of BC is 22 units.
