Using the angles sum and difference identities, we are able to expand the trigonometric expressions, thereby obtaining the values of the non-variable terms. The variable terms are easily simplified by combining like terms and solving for x. To solve for x we will need to isolate the trigonometric functions and apply inverse trigonometric functions and the unit circle to solve. The appropriate range is applied to get the required value of x.\n
