x=9.4cos(58°)

because the cosine function uses the ratio of the adjacent side to that of the hypotenuse.

9.4 is the hypotenus the ration is 58 degrees I believe

[tex]\\ \rm\Rrightarrow cosA=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\\ \rm\Rrightarrow cos58=\dfrac{x}{9.4}[/tex]

[tex]\\ \rm\Rrightarrow x=9.4cos58[/tex]

Option D
