Or, in other words, which angle has a cosine of 0? There are actually two angles that return this value: 90 degrees and 270 degrees. But by definition you know that every angle in a triangle must be less than 180 degrees, so that leaves only 90 degrees as an option. kitchen color schemes for small kitchens
