The law of cosines generalizes the Pythagorean theorem, which holds only for right triangles: if the angle Оі is a right angle (of measure 90 degrees, or ПЂ / 2 radians), then cos Оі = 0, and thus the law of cosines reduces to the Pythagorean theorem: = +. Two sides of a triangle are 8 units and 12 units long. The angle opposite the 8 unit long side is 35В°. What is the angle opposite the side that is 12 units long? We know two of the sides and one angle of the triangle, and our unknown variable is another angle. вЂ¦
