Answer:
can we have the worksheet?
Angl G = angle I because of alternate interior angle theorem
the triangle JHG is congruent to the triangel JFI because the corresponding angles F and J equal with J and H in the other triangle and the sides between them are equal FJ and HJ
therefor GJ = IJ because of the congruence
You would need to distribute the 3 on the left side and the -6 on the right side. p=7/3
It would be a rotation I believe
