If one angle is 57 degrees and the second is 2 times the third, what are the three angles?The sum of the angles in a triangle is equal to 180.Let 57 be the first angleLet y be the second angle Let z be the third angle57 + y + z = 180The second is 2 times the third or y = 2z57 + 2z + z = 18057 + 3z = 18057 - 57 + 3z = 180 - 573z = 123z = 123/3z = 41
