Answer:

BC=24

Explanation:

We know that in an isosceles triangle if two angles are congruent then the opposite sides of the angle must also be congruent.

Therefore
AC=AB

Then we can create an equation and solve for x

$x+8=2x-1\\x+9=2x\\9=x$

Now that we have x we just need to substitute it for

$BC=3x-3\\BC=3(9)-3\\BC=27-3\\BC=24$
