Sin(x) = opposite over hypotenuse  Cos(x) = adjacent over hypotenuse Tan(x) = opposite over adjacent Everything revolves around a right triangle. From the given equation, "sine of x equals square root of 2 over 2" Opposite = square root of 2 Hypotenuse = 2 Adjacent = ? Using the Pythagorean Equation: H^2 = O^2 + A^2 2^2 = (square root of 2)^2 + A^2 A^2 = 4 - 2 A = square root of 2 Cos(x) = square root of 2 over 2 Tan(x) = square root of 2 over square root of 2 = 1
