    The legs are congruent if is an isoceles triangle.

    So you set it equal to each other to find x. After you did that, plug the x into the base length 3x-3

    Whenever an isoceles triangle is congruent, its leg are the same in length. Since the legs have lengths x+1 and -x+7. You must make them equal to each other by solving for x. After you solve for x, plug that x back to the base, since the base relies on the x to figure out its length.

    Set them equal to each other x+1=-x+7. Know this? It is from Algebra 1

    Yes, but I barely remember it. What number do I subtract from each side? @Shalante

    make the x into one side, so you add x to the left side and the right side.

    But there's already an x on the left and right side? @Shalante and i dont have a lot of time left to finish my exam..
