Answer:
As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).
Step-by-step explanation:

Answer:
E, F, A, ED, BC, EF, ABC, EDF
Step-by-step explanation:
The angle and side markings show which segments and angles are congruent.
We can make a table of corresponding pairs based on the number of marks:
marks, angle, side
- A and E, DF and BC
- B and D, ED and AB
- C and F, EF and AC
__
This can help us fill in the question numbers:
- ∠E is congruent to ∠A
- ∠F is congruent to ∠C
- ∠A is congruent to ∠E
- ED is congruent to AB
- BC is congruent to DF
- EF is congruent to AC
- 8. ΔABC ≅ ΔEDF
