Answer:
x = 22
Step-by-step explanation:
Sides AC and AB are equal, because this is an isosceles triangle.
Therefore, 2x - 24 = x - 2.
Subtracting x from both sides yields x - 24 = -2, and then adding 24 to both sides yields x = 22.
BC = 22
∠ACB = ∠ABC , hence ΔABC is isosceles with
AC = AB ← substitute in values
2x - 24 = x - 2 ( subtract x from both sides )
x - 24 = - 2 ( add 24 to both sides )
Hence BC = x = 22
