1. The problem statement, all variables and given/known data Someone gave me this problem: finding the radius of the circle inscribed in the triangle with the given lengths. 3. The attempt at a solution The person asking about this problem said it was taken from a beginning algebra textbook. I tried figuring it out using just basic algebra, but I couldn't make any progress. Is this problem solvable with basic algebra/geometry? Would it be any easier if it were a right triangle?
