Answer:
(C) Infinitely many solutions
Step-by-step explanation:
Converting the lines into the from 





So,
.
Hence, these lines have infinitely many solutions.
Answer:
rectangle, quadrilateral, and square are all right. maybe kite too but I dont think so-
Assuming that there are N lanes and runners are running in the middle of each lane,
width of each lane = (1/N) [m]turning of first lane = π×(R+(1/N)×(1/2))
turning of second lane = π×(R+((1/N)×(1/2))+(1/N))
you can get the difference in turning lane simply by subtracting turning of first lane from turning of second lane.
If i worked the problem correctly, it should be π×(1/N) meter difference between each lane
Tell me if the answer was true
