I'm assuming you have two congruent triangles, triangle ABC and triangle XYZ !

I'm assuming the length of segment AB=26 and the length of segment XY=4x+2.

In my diagram the measure of AB=the measure of XY.

Therefore 26=4x+2

24=4x

6=x

The congruent triangles may be result of the reflections, translations or rotations. And length of YZ is just additional information, we can assume from the problem.

Hi Vivian;

Good points ! We, as tutors, are at a disadvantage because we don't have a diagram to look at. We sometimes have to assume certain things, which is what I did. I just assumed(again) that the information YZ=30 was put in as extra info to see if the student could determine what was relevant to the solution and what was not. Maybe the student will give us more information.
