Answer:
See image
Step-by-step explanation:
See image. You can use rigid motions, which don't stretch the shape. The possible rigid motions are reflection (flip) and translations (slide)
Obviously there's more than one way to slide triangle ABC onto triangle EDF.
See image. You could reflect the triangle over the y-axis. Then translate the shape left 2 units and down 4 units. Then triangle ABC will slide right exactly onto triangle EDF showing that they are congruent.

Answer:
x = 45/7
Step-by-step explanation:
Here, you can more easily see what the fractions look like.
In order to cross-multiply, you have to multiply 5 with 9, and 7 with x.
45 = 7x
Then, you isolate x by dividing 7 on both sides:
45/7 = x
