Math Question

16. The degree measure of an angle in a right triangle is \( x \), and \( \sin x=\frac{\sqrt{2}}{2} \). Which of these expressions are also equal to \( \frac{\sqrt{2}}{2} \) ? Select all that apply. \( \begin{array}{l}\cos (x) \\ \cos \left(x-45^{\circ}\right) \\ \cos \left(45^{\circ}-x\right)\end{array} \quad \sin x=\frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2} \) \( \cos \left(60^{\circ}-x\right) \) \( \cos \left(90^{\circ}-x\right) \)
