Final answer:
To find x, AB, BC, and AC, we can use the fact that B is the midpoint of AC. This means that AB = BC, and AC = 2AB.
Step-by-step explanation:
To find x, AB, BC, and AC, we can use the fact that B is the midpoint of AC. This means that AB = BC, and AC = 2AB.
Let's assume that AB = x. Since B is the midpoint, BC is also x. And since AC = 2AB, AC is equal to 2x.
So, x = AB = BC, and AC = 2AB.
