The solution to Problem #302 as posted by lindell is not correct.
Problem #302 has the following statement:
"An equilateral triangle has been added to the arbelos of Problem #300.
At what distance should point C' be from point A to make all three full circles the same radius if AC'=BA'=CB'?"
Now one will have to look at both Problems; Diagrams and wording.
No where is any distance given in either Problem so NO numerical solution can be given as lindell does for Problem #302. lindell ASSUMES in his solution for Problem #302 that BA = 1. Where is this distance given in either of the Problems 300 or 302.
A solution to this problem would have to be with the letters given: B,C',A,A',B' and C as given in the problem. I want the distance BA to be pi. Now lindell's solution is incorrect.
The solution "what is the distance from C' to A is: An infinite number of solutions.
