Question

BRAINLIST GIVEN What is the length of BC¯¯¯¯¯ ?

Answer 1

The angles at the base are the same measure. Hence, this is an isosceles triangle |AC| = |AB|.

Therefore we have the equation:

$2x-24=x-2$            add 24 to both sides

$2x=x+22$            subtract x from both sides

$\boxed{x=22}$

Answer: |BC| = 22

Answer 2

since the ∡C = ∡B, that means their corresponding sides stemming from the vertex A are equal, namely AC = AB.

2x - 24 = x - 2

x = 22.
