Question

Last one for the night lol thanks again

Answer 1

`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`

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