Step-by-step explanation:

Answer:
yes, ASA
Step-by-step explanation:
You have two angles and the included side of two triangles, so you can prove the triangles are congruent by ASA.
Well the answer is x^2 - 16x + 63
The triangle was only rotated. The size did not change, so the corresponding angles would remain identical.
Because C is 28 degrees C' would also be 28 degrees.
