Thanks so much for the quick reply.
This page is assuming that the triangle is a right triangle though.
In my case there is no information given whether the triangle is actually a right triangle or not.
Thanks for the reply earboth.
I thought that it was unsolvable as well.
I was just a little confused because this question was on my math test and when I asked my teacher if it was solvable she told me that it was.
I think she may have just written a flawed question.
Anyways, I really appreciate the quick responses.
