Best ResponseYou've already chosen the best response.0So you set it equal to each other to find x. After you did that, plug the x into the base length 3x3

Best ResponseYou've already chosen the best response.0Whenever 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.

Best ResponseYou've already chosen the best response.0make the x into one side, so you add x to the left side and the right side.
