Bitter areas.

Hi;

3 listening posts are situated in the north atlantic. They form an equilateral triangle. A nuclear explosion takes place 500 miles from one listening post, 1200 miles from another and 1300 miles from the last listening post. The explosion takes place inside the triangle that the posts form. What is the area of the triangle that the listening posts form?

A says) Impossible to determine, Cauchy wrote a paper on it and I am well familiar with that paper. It is a great advantage that I enjoy knowing more theory than B does. I know when a problem can not be solved, B does not. That is why I can work on the ones that can be solved.

B says) Hold on A, the problem is easy using...

C says) Cauchy hmmm, I have heard of him.

D says) Yes, he owned a bakery on my block and made good cannoli.

C says) Weren't they first discovered by Schiaperelli?

A says) Yes, I read a paper about the cannoli's on Mars, they were found to be a hoax. Something B probably knows all about and believes.

E says) What the heck are you talking about? I hate idiots and A,C and D qualify. I have already solved the problem.

Can you?

Re: Bitter areas.

Not really, the spin distorts the shape. For the sake of the problem a flat plane was considered okay.

Re: Bitter areas.

Well. I am getting analytically the same result as phrontister. There is also a solution for the blast to occur outside the triangle formed by the posts.Then the area will be

sq.miles.

Re: Bitter areas.

Hi;

If you got the same answer as phrontister you have solved the problem. Good work. The other answer violates the terms of the problem.

Re: Bitter areas.

Hi;

Yes, that is a solution and it makes good use of the new Region commands. Very good.
