Weegy: While what follows doesn't rate as a vigorous proof, the symmetry and continuity of the equation suggest we only need to check a small number (three, to be exact) of triangles to determine what K should be. [ Basically, we can look at the delimiting situations for the triangles and see which one has the smallest value for K. First situation, a 45-45-90 triangle: This is the delimiting situation for a "barely obtuse" triangle where the acute angles are equal. For this triangle, a = b = 1, c = v2, and we calculate K = (1+1+2)/(1+1+v2)? = 2/(3 + 2v2) ~ .343. Second situation, a 0-90-90 "triangle": This is the delimiting situation for a "barely obtuse" and flat triangle - the obtuse angle is approaching 90? and the length of the shortest side is approaching 0. For this situation, a = 0, b = c = 1, and we calculate K = 2/3. At this point, let's note that (a) the equation is continuous and (b) the interchangability of a and b give the solutions symmetry. So, K for any other "barely obtuse" triangles would necessary fall between the values for K for the two situations just considered. (For a demonstration of this, try a 30-60-90 triangle: a = 1, b = v3, c = 2. K calculates out to 4/(6 + 3v3) ~ .357.) There is one other delimiting condition, and that is for "extreme obtuse" triangles, where the obtuse angle approaches 180?. For this situation, a = b = 0, c = 1, and we calculate K = 1. Since this is the largest value yet for K, it is apparent that K gets larger as the angle gets more obtuse. Hence, we can conclude K = 2/(3 + 2v2) ~ .343 is the largest value for K that makes the equation true for any obtuse triangle. ]
