a. $\text{cos}(57^{\circ})$

Step-by-step explanation:

We have been given that when solving for x, the sine of 33º is used.

We will use property $\text{sin}(x)=\text{cos}(90^{\circ}-x)$ to solve our given problem.

Upon substituting our given values in above property we will get,

$\text{sin}(33^{\circ})=\text{cos}(90^{\circ}-33^{\circ})$

$\text{sin}(33^{\circ})=\text{cos}(57^{\circ})$

Therefore, $\text{cos}(57^{\circ})$ could be used to solve for x and option 'a' is the correct choice.
