Finding radii for circles inscribed in a triangle

I have a problem I am working on from a book in a pdf format, so I have a screen capture of the problem. It seems that this forum does not allow me to upload my photo though? I must upload it because it is a diagram that would be difficult for me to describe accurately. Any ideas on how to post the ...

Re: Finding radii for circles inscribed in a triangle

That's exactly what I was looking for. It's strange to see them using a theory/postulate(?) to solve the solution that I wasn't taught yet.

Trig Functions on the Cartesian Plane  TOPIC_SOLVED

Hello all. I am working on finding the trig rations of angles that go through a set of x-and-y coordinates ( x , y ). I was doing pretty well; doing the problems, then confirming my answer with the back of the book answers. Then I got to the point ( -10/3 , 4/3 ). X and Y are obvious as they are giv...

Understanding Zeros Theorem Proof  TOPIC_SOLVED

I am having trouble understanding the proof in my text for the Zeros Theorem. It goes like this: "Proof: Let P be a polynomial of degree n. By the complete factorization theorem P(x) = a(x-c1)(x-c2)(x-cn) //the numbers and letter n and i are subscript Now suppose that c is a zero of P other tha...

Re: Understanding Zeros Theorem Proof  TOPIC_SOLVED

So when they say 'c i ' they aren't using i to mean sqrt(-1)? The use of 'i' has really confused me. EDIT: A question I forgot to mention in my OP, how is there a zero, c, that is not c 1 ,c 2 ....c n ? I understand that every polynomial has a value that will result in the polynomial equaling zero. ...
