Hello amazing people of the Education & Training Community!
Here I am once again to guide you through the step-by-step procedure for solving a trigonometry question that leads to a quadratic equation.

The reason we need to transform the equation into a quadratic form is to enable us to solve it using the appropriate quadratic formula, which allows us to find the required value of cos X = Y.

Once we obtain cos X = Y, we then determine the values of X (such as 1 and 1/2) by using the trigonometric table to find the corresponding angles in degrees.

Finally, we identify the complete set of values for X as 0°, 60°, 300°, and 360°, all within the range of 0° to 360°, as clearly stated in the question.
